When "20's" was first announced, I remember just skimming over the information. The only reason I paid any attention to it at first was because Kikwang was in here- otherwise the news would have slipped my mind. Then there was an article about this drama on my favorite blog- and then Viki kept on advertising it, so how could I resist? Story: "Twenty Years Old" touts itself as a bit of coming-of-age story, but at barely two episodes long, this is less of a growing-up story and more of a fluffy romance- the type of cute you wanted from all the drams you watched, but never got due to random plot mechanisms. If I had to guess, about 60% of this story is random cute, and the other 40% makes a valiant effort at the aforementioned growing up. The lack of actual substance would annoy me- if it wasn't for the fact that Lee Da In and Kikwang are absolutely *adorable* together. Seriously. They're ridiculously cute. The supporting characters- like Ga Young and Hye Rim's schoolmates, were charming and interesting to watch- even if their screen time was next to nothing. Something that kind of irked me was the story format. The director really overused the reverse-time format here, so if you don't keep up with the time in the first two episodes, it's *really* easy to get lost. I'm going to let it slide because this was a mobile drama, so experimenting with the format is a given. Other than that, the directing was actually really great- full of really interesting camera shots and gorgeous cinematography. Acting: While I wouldn't say Kikwang and Lee Da In are amazing off the bat, they do have a lot of potential. If they work on their acting, they could definitely go places. Kim Hye Ji was also really nice in her role- again, not amazing, but she can get there. Hye Rim's school sunbaes were also portrayed by good actors, so I can't say that there was any bad actors. Music: There really wasn't all that much music in here- except for a few random BEAST songs or an instrumental or two. Rewatch Value: I guess it depends. I would probably rewatch "20's" after being horribly burned by some other drama's main couple, but I don't really see myself rewatching "Twenty Years Old" just for the heck of it. Maybe I will? Overall: Ridiculously cute, but I find it hard to remember anything beyond that. Maybe you will like it better than I did?
