If you are expecting big booms going all the time thinking that this is a movie about nuclear bombs and should have it every other minute, then this is not the movie for you. Also, you might not like the pacing of the movie, which I will be honest, felt slow and boring at times. However, if you are a person of patience and like the slow build up of tension and drama, this is the movie for you. Extra dibs if you are into Physics or Science in general.
I am only giving 4 stars because I got bored at times. Ignore the 1star reviews and the over zealously written 5 star ones; because they probably do not know what they are writing in the first place.
