The overall very entertaining film does get a bit slow in the middle part, could have used some editing there, and is far from action packed in the first place, but keeps you on the edge of your seat with its characters and interesting questions about moral and time travel with all the mess it entails. The script handles that really well and is backed up by great cinematography, with several very unique and impressive shots. The result of the really exciting showdown will open up interpretation discussions, and what more could you ask of a movie.
