I honestly enjoyed this movie, I had no idea of the twist at the end, I was wondering how can they be on a train in the beginning of the movie when later it goes back in time it seems and there seems to be a definite end to things.
Loved the twist.
I legit cried a bit too when I thought that is it.
To me this a love story. That transcends time and space.
They are soul mates I feel.
Don't decide not to watch it by reading the bad reviews, watch it and decide yourself.
