So... I started watching this drama because I was curious about this Korean remake of the movie 17 Again. I remember liking the film (I even have it on DVD) so I really wanted to see the Korean version. And... I have mixed feelings about it.

First of all, the story. Well, it's basically the same from the movie (at least, for the main plot). Because, of course, you can't make a remake of a 1h45 film into a 16h drama without developing the initial story. But, if the story was pretty good at the beginning, it became more and more filled with drama... Too much drama... I ended up really annoyed by all the useless drama that they have created. Moreover, there are too much clichés!!! They have used all the typical romantic clichés that we usually see in K-drama and that became more annoyingly funny than romantic at the end... They could've been more creative about that. Also, I think they made some really bad decisions with the main plot (but that's just my opinion). For example, the scene where he goes back to his old self was more impactful in the film than in the drama.

The casting was the only thing that was perfect in this drama. I mean, Lee Do Hyun killed it in the role of a young dad. He made me laugh, he made me cry. I really fell in love with him in this drama. I'll always remember the scene where he was holding the umbrella for his two children, that was so cute. Or the scene where he signs to his dad after the basketball match. The rest of the cast was also good, of course, but Lee Do Hyun stole the show for me.

The music is really good, although overused.

As a whole, I would say it is a good show to watch once. Prefer rewatching the film instead, it will take less of your time.
