Before writing this review, I watched this drama through twice, back-to-back. The first time was a full watch, from start to finish, with not a single second skipped, while the second time was a speed watch, where I skipped over scenes and plots that didn't especially hold my interest the first time around and paid more attention to the main storyline/lead couple.

I want to start this review off by saying... Overall, I definitely enjoyed this drama. It gets points right off the bat for being a unique if not incredibly ambitious drama. W tells the story of Oh Yeon-joo (played by Han Hyo-joo), a (somewhat struggling/untalented) cardiothoracic surgeon who happens to be the daughter of Korea's most beloved webtoon/manhwa artist, Oh Seong-moo (played by a scene-stealing Kim Eui-sung). Seong-moo's creation-- W-- is lead by main character, Kang Chul (played by Lee Jong-suk), an extremely successful and wealthy, self-made, former gold medal Olympian in shooting, who's family was murdered by an unknown assailant ten years before the start of the series in the comic book's version of Seoul.

After Oh Seong-moo's wife leaves him, taking Oh Yeon-joo with her, the artist struggles with alcohol abuse and suicidal, self-destructive ideations. He uses his creation, Kang Chul, to act out his own cowardly desires and self-destruction, but the strong-willed main character who fights for righteousness refuses to go down without a fight and accept the death his artist chose for him. From that point on, Chul continues to fight against Seong-moo's intentions and drawings, increasingly derailing Seong-moo's attempts to sabotage his creation, who he grows more and more frightened of with each defeat. When Seong-moo makes one last, desperate attempt to destroy Chul, both he and his daughter are pulled into the world of the webtoon, and their immediate actions upon landing there will have deep repercussions for the webtoon, the characters within it, and the real world they are from.

When I say this story was ambitious, I mean it. There are essentially two casts, the cast of the webtoon which consist of Chul's nearest and dearest, the villains that pursue him, thugs he regularly faces, and a slew of background characters, and then the cast of the real world, populated by the apprentice artists in Seong-moo's studio and the other doctors and residents at Yeon-joo's hospital. Chul's version of Seoul is filled with penthouse apartments, high-end boutiques, and sports cars. Yeon-joo's version of Seoul is filled with overworked doctors surviving off naps in a cramped break room and manic, demanding superiors. Chul's world is filled with the excitement, adventure, and thrill that made W so popular with readers, while Yeon-joo's world would be boring if not for the webtoon beginning to bleed into it. I think the series does a good job of differentiating these worlds, even though we're repeatedly reminded that not only are they taking place in the same city, but many of the buildings appear in both (just with different names).

There are a lot of special effects throughout the series that are in and of themselves kind of a character in the series. Production didn't seem to spare any expense when it came to them. We see cartoon panels draw themselves, characters and items be drawn into existence out of nothing, and characters appearing and disappearing as they fulfill their purpose or fight against it. Considering the world they were creating, the effects are sound and impressive.

That said, the series may have been a little -too- ambitious with the story they were trying to tell. The rules for the universe seem to change on a dime and be inconsistent. Chul seems to explain these away as "variables," but it's mostly just inconsistent story-telling. Rules exist for something when convenient, and when they get in the way of advancing the plot, they're suddenly abolished for no apparent reason. For example, we learn early in the series that Chul (and other key characters in the series) are able to pull Yeon-joo into the webtoon just by thinking about her. The magic drawing tablet (a character unto itself and the most inconsistent of them all) doesn't have to be on or functioning for this to happen, the character just needs to need/want her for it to happen, yet at the end of the series, Yeon-joo is stuck outside of the webtoon for a year of webtoon time because.... Honestly, I have no idea, and I watched it twice. It seems like they try to tie it to the tablet being turned on again, but we've seen her travel without the tablet functioning/being on before, so why? It was just what they needed for the story, I guess. Those inconsistencies and plot holes are frustrating, to say the least.

Character-wise-- and I really hate to say this-- I think Kang Chul is the weak spot. Let me immediately clarify by saying this is in no way a condemnation of Lee Jong-suk's performance! He is electric on the screen. Eyes are drawn to him and his charm is undeniable. The disconnect is on the writers/material he was given. Kang Chul is just-- to me-- a bit unlikeable and inconsistent. Chul's relationship with Yeon-joo feels decidedly imbalanced, especially their first go round, but also still in their second. Yeon-joo wears her heart on her sleeve for Chul, the ideal man she dreamed up as a child, but the affection often feels one-sided to the point more than once I experienced a kind of secondhand embarrassment on Yeon-joo's behalf. By the end of the series, I can accept them as a couple, but even then, to a certain degree it feels like Chul has just accepted Yeon-joo as his fate (even though he insists he chose her).

The best acting in the series comes from Han Sang-hoon, who plays the double role of both Yeon-joo's father and the murderer of Chul's family and his greatest enemy. He swings back and forth between the roles in a moment's notice, invoking fear then sympathy, followed by psychopathy and patheticness in dizzying succession. If you're a crier like me, Han Sang-hoon will pull a few tears from you in the finale, I can promise you that. Lee Jong-suk and Han Hyo-joo each perform their roles well as the leads. Lee Si-eon as Oh Seong-moo's apprentice Park Soo-bong and Kang Ki-young (who I adore!) as Yeon-joo's fellow resident surgeon Kang Suk-beom are great in their supporting roles. I never really warmed up to Jung Yoo-jin as Yoon So-hee, Chul's assistant and expected love interest and Lee Tae-hwan as Seo Do-yoon, Chul's bodyguard and best friend. They both felt a little one-dimensional and one-note as characters, but maybe that was intentional since they're supposed to be manhwa characters... I don't know. Either way, the characters around Yeon-joo definitely trumped those around Chul.

The music in W is, in a word, fantastic. I bought the OST right away after finishing the series a first time. I'm a little reluctant to admit that Jung Joon-young's performance of "Where Are U" is a standout given who he turned out to be, but the song really is great. The hip-hop track, "In the Illusion" by Basick, featuring Inkii is an unexpected gem. "Without You" by N of VIXX and Yeoeun of Melody Day is great, as is "Falling" by Jo Hyun-ah of Urban Zakapa and "Please Say Something, Even Though It's a Lie" by Park Bo-ram. I'm a big fan of KCM, but his song "Remember" is the weak spot of the OST.

I would definitely say W has rewatch potential. I caught things on the second go-round that I had missed the first time, so I'd even go so far as to say repeated watching would be a good idea. I think it's especially true since there is a lot of complexity to the plot, and it was overall easier to follow and understand in my rewatch than it was in my initial viewing. I've seen it twice now and I'll probably give it a third watch at some point in the future. It hits a lot of good notes; there's action, adventure, love, and sacrifice. It's not a drama to have playing while you're doing other things; it requires focus to follow, but it was more fun the second time around, so I would definitely encourage rewatches.

Overall, I enjoyed it. Is it perfect? No. Are the characters and writing perfect? No. Is the world-building perfect? No. But is it enjoyable? Yes. Do I regret watching it? Absolutely not. So give it a chance. It's a pretty good way to spend sixteen hours.
