Crash landing on you is a story about belonging and community
Soon ri and numerous characters are avatars through which we can see this
yae ri finds a community amongst the north koreans
The north koreans find that they fit in a bit too well in south korea
The random mom of the second female lead was like a super bitch but she end up being good friends with the villagers.
Joon hyuk and Soon yae ri ended up being such a good match that they ended up together outside the drama as well.

Perhaps in another universe, north and south korea could have been one great big loving community.
But koreans are evil so that aint gonna happen

Anyways Crash landing onto you maintains a good balance of drama, plot while adding in little specks of dogshit here and there to take away the emersion and make you feel like youre watching my love from the stars.

The music is used effectively, though some of it is overused (standard for most kdramas).
The acting was sometimes goofy but mostly solid. Besides caricature moments, it was actually pretty good. The goofy special forces was comedic relief but actually had enough personality that they werent just annoying plot devices like in many other shows.
The overall quality is fairly good like the cinematography, though heavy cuts such as in fight scenes did give me a slight headache. Shit would have been a peak ending if the camera panned and focused on the special flower in Switzerland right at the ending. Still enjoyable but missed opportunities.
The middle and latter parts of the show were better, mainly focusing on character development and actual plot (something that is missing from many kdramas *cough cha cha cha). Minor parts of the story weaved into the overall plot pretty well, and besides the suspension of disbelief, it’s a fairly enjoyable plot.

God forbid a character actually learn and have development. I cannot believe how many shows Ive seen where the main character is static, does jack shit and just waits like a damsel in distress. Soon ri is a bitch but she gets better (stops being korean). As always, the second leads were more interesting/had more chemistry but cant really say anything, when the main two leads got married irl.

Edit. After finishing the show, the second couple story was peak. The main couple was done enjoyably. Decent ending. Could have been potential for inserting the opening into the scene where they are in north and south korea and bro is doing the voice over. A bunch of misssed opportunities but still quite enjoyable.
Overall, besides minor complaints and the first half being hella boring, it’s a surprisingly enjoyable show.
