There is not a single scene in which the characters are not chattering incessantly.
There is not a single second in which the audience can listen to its own thought.
The plot is bland, the writing is below mediocre.
And that scene. The infamous scene in which the whole world is going to hell and the character yells "my son!" unironically.
Nolan thinks he's a genius, but he's just cringeworthy.
With that said, Robert Pattinson's acting is excellent.
