If this drama is a plate of food, it had the best ingredients and beef but the chef is panicking so he added all the spices available in the kitchen, then overcooked it because he's afraid the meat will be rare. Because they have to make a 16 episode drama, they give you a lot of side stories forcefully crammed in the storyline. To be fair, sometimes I complained because the supporting characters are not given enough story depth, but 18 Again was too much in doing that. Most of the latter half of the drama is filled with all these stories and they successfully reduced my interest. I also admit that I loved the comedic parts of these stories but no, we don't need the stalker, we don't need Ye Ji Hoon's brother and his story, probably Choi Il-gwon is not necessary too. There are already enough flashbacks and more important side stories to focus on.

The casts are doing good job in their roles, especially Lee Do Hyun who successfully portrayed the 18-year old and 37-year old parts. There is no awkwardness when he is in romantic scenes with Kim Ha Neul. Yoon Sang Hyun on the other hand also managed to express frustrations and regrets to the viewers very well.

Music is generally nice, but not that super memorable. Why? Blame "Hello" for that. The song is a bit overused and in the end your mind just randomly playing "hello... hello...". So yes it managed to stick on me, but as a nuisance.

Overall this drama is quite enjoyable because the story is actually nice and full of life lessons, just skip the unfunny side stories.
