I did not expect something super cool or even interesting. Surprisingly it's a good movie that is worth watching. Scenario is catchy with a lot of twists, the cast is very good, and overall the quality on a high level.
If you like Christopher Nolan and Steven Spielberg movies then you will like this movie as well. This movie kind of reminds me about "The Butterfly Effect" (2004), "Deja Vu" (2006), "Source Code" (2011), "Looper" (2012), and "Predestination" (2014).
P. S: Importantly, do not expect something tremendous, It is not a movie with a Hollywood budget. I assume the team did not have a lot of money. However, the team did a really good job. Anyway, it is a nice movie and of fine quality.
