The movie was unnecessarily long and complicated. The whole time I just felt like it was a pompous attempt by the director to make a flashy and confusing movie that requires the audience to watch a few times to understand.
An enjoyable movie-going experience for me should be one that you feel touched or inspired by the characters and plot. Instead, this one you just feel kidnapped and frustrated and exhausted.
Cillian Murphy was great, but all the other actors were just ok. The movie topic is quite interesting and makes you want to research and find out more.
