Train had a good payoff and finale but it was a bit of a slog getting there. For a suspense crime noir drama, the pacing was so off. It's only 12 episodes but the 'thrill' part is lacking, there were lots of fillers and rehash of past stuff. There's even not enough travelling between worlds to make the parallel worlds concept more exciting. The music is lacking as well.

I wanted to check this out for Yoon Shi Yoon. He played the dual roles well, but felt he can go a tad overboard at times. His trademark charisma is evident though even in such a serious role so I'm curious to see him in a comedic role next. The cast was more or less forgettable. The actor playing the villain was so bland. His background is interesting enough, but that actor lacks the villain gravitas. I liked that final twist though, and how it all comes together by the last 2 eps.

That romance is weird. Interesting concept but I wished the male lead did not like the girl instantly just because she looks the same as his first love. Hope the writer took time to develop the feelings first. In the end, this is a drama I can only strongly recommend to Yoon Shi Yoon fans.
