What I usually dislike about the usual "follow your heart and do what you want to do" kind of stories, is how the characters are rarely placed in a context where they can doubt of themselves in a realistic way: it usually feels like they're held back by self-doubt only, while everything else (physical and mental condition, friends, family, money, and so on) is completely in their favor, making it hard for me to relate to their story at all.

Navillera is one of the very rare shows that actually made me think that I, too, might be able to follow my heart after all. The charm of this drama is not just in its premise (although, I'll be honest, the idea of a 70-year-old man wanting to learn ballet was the major reason why I got interested in the first place), but also in the way it narrates the story. It's realistic and vivid, and none of the characters are there for no reason. The doubts and struggles of Deok Chul's family, and the problems of Chae Rok are all very much real. Rather than watching a drama, it really felt like looking into someone else's life.
For the same reason, the drama felt a little slow at times, but it was the right pace to show everything the right way: it was necessary to show the mind of the characters and the events around them, and it was useful to lead all the plotlines to a worthy conclusion.
I had read the webtoon before and really loved it, so I can't say I wasn't a little skeptical about the drama at first. There are some differences that I couldn't ignore, but I guess it was unavoidable.

Overall, I highly recommend this drama. It made me cry multiple times as I watched, but I'd be more than okay to cry again in the future while watching a second time.
