A time-traveling mystery that's not your typical fluffy teen drama.
Subjective Gut Rating: 7.75
“Blue Birthday” is definitely very different from what I expected. I thought this would be a simple time-traveling sweet rom-com where the female lead finally got to confess her feelings and then something happened and they end up living happily ever after. NOPE! This is not that kind of drama.
I did get a few things right - time-traveling, cute and fun friend groups, adorable couples and romantic feelings here and there. These are to be expected in any teen drama. But if you are expecting fluffy romance, the second half of the drama proves that is not the case. I don’t want to spoil you, but if you are a veteran K-drama watcher, you know how K-dramas like to throw in a thriller component to many of their romance dramas. Afterall, there is a ‘thriller' tag here.
This is the female lead, Ye Ri’s first main role, and I think she did respectably but not amazingly. At least, she is the best of the bunch. She’s adorable when trying to be cute, and her emotional scenes are done right. In contrast, male lead Yang Hong Seok has more dramas under his belt, yet he’s not as good as Ye Ri. He’s cute, but his acting is inconsistent. He was pretty emotionless in the first half of the drama, but seems to have relaxed a little bit in the second half. The rest of the friend group is fine. The villain though, definitely gives off crazy, psycho vibes (maybe just a tad of overacting).
The fantasy element and time-traveling are interesting, though not explained as to why it happened to them. The drama did try to explain certain elements of time-traveling in words during the epilogues. I do applaud the drama for trying to do something different from a normal teen drama. The plot twists are interesting. Given this is a lower budget drama with short run time, the drama scratches the surface of these twists instead of really taking the time for a better buildup and execution.
This is a Friend’s Drop List Challenge watch for me. I picked it because the plot seems interesting and it’s short. I don’t regret my selection even though I was looking for something a little lighter and fluffier. If you are looking for a sweet and fluffy teen romance drama, this is not it. But if you want to try something different in a time-traveling drama with a dash of friendship, slight romance and mystery, this is a quick and easy watch.
