It's a 3hr 10min super long & boring documentary on a legal case against Robert J Oppenheimer.
Probably his worth movie till date.
Nolan wasted the time and the opportunity to make this a brilliant movie.
Rather than wasting time on the chatter of the legal case, Nolan could have focussed on the dynamics of making the Atomic bomb - the why and how it was made and what did it do.
This might please select movie critics but isn't for a balanced audience.
I had trouble staying awake. Imagine - The overdose of caffeine (850 ml large coke bottle) couldn't keep me awake.
Lesson for the day......
Never prebook tickets trusting the hype!
