An amazing movie with a perfunctory ending!

Rating: 7/10 (25 September 2019)

The story is about the future when the time traveling is available but it's only used in secret by the biggest criminal organizations. It sounds logical that the time traveling would be illegal but there was a rule that everyone should closed their loops and I wasn't really convinced about it.
It's a story of an old man who has nothing else to lose and wants to save his wife's life by going back in time and he decides to do anything necessary no matter how cruel it would be.
There are many scenes that the old man is confronting his younger self and both sides hate each other as much as possible.
In such movies, there is always a battle between a good guy and a villain but in this movie you cannot distinguish it. One of the most interesting things about this story is that you cannot prognosticate what comes next.
The story was really fascinating and I just don't understand why it had to end that way. I don't repudiate the fact that there was great casting and interesting story but the ending was awful and it kind of ruined the whole movie.
