Although the plot was everything but stable I still found myself to enjoy this movie despite the sometimes rather off-putting soundtrack. The reason? It's simple. Namely, the actors playing the twins. Although the plotholes in the script were as many as holes through cheese, the dynamic between those two the few scenes we could see them together made me stuck to the screen watching. Although the actors playing the grownup twins were superb in my opinion, the actors playing the teenage twins should nonetheless have some huge credits too. Especially the one playing Taesung. The raw emotion that kid emits, damn.

I don't highly recommend this movie, but I recommend it nonetheless (If only for Sung Hoon's spectacular visual in it). I wouldn't even say no to some time in the future watch it again and see if I notice even more subtle details from the two ML's acting.
