Initial thoughts after watching this for the first time:

Clearly a great film in the cannon of Christopher Nolan’s catalogue. However, it didn’t need to be 3 hrs long. The film peaked at the Trinity Test, and then went into a courtroom drama for the last hour. This was interesting but in no way met the dramatic tension of the Manhattan Project.

I like the fact that it didn’t dumb down and there’s a lot of assumed knowledge about this era for the viewers. 

The score wasn’t as overfacing as other Christopher Nolan films and as always there’s plenty of beautiful cinematography to chew over.

Not an immediate rewatchable but I can understand why it won the Best Picture Oscar nonetheless.
