I am not a fan of Nolan, never was, but this is more than just a matter of taste.

The first hour or so seems like an eternal movie trailer, with hyped epic music and painfully neurotic short cuts (I don't know if the whole movie has a shot longer than 3 seconds).

Now, onto the dialogues: they are insufferable. Nolan apparently sees his viewers as complete idiots who know nothing, so the dialogues are crammed with unnecessary information. This especially sounds ridiculous in dialogues between 'scientific geniuses' - they are full of information that participants in the dialogue already know ("He's Einstein, the father of relativity" etc.).

Sex scene. Who the hell stops in the middle of sex and goes to the bookshelf to admire books someone has? Really?

Character. Nolan basically figured out long time ago that the best way to develop a character is to put him in an ethical dilemma. And, apparently, the only way. So with Oppie here, we are just looking at another Dark Knight, who now appears to be a nuclear physicist.

Not to mention the worst part of it - the whole movie is about whether what he did was ethical and whether he is an American patriot, and not about probably the worst thing that happened in that war after the Holocaust! I may not be a history buff, but these tour the force bombs obliterated a couple of hundred thousand people, making it one of the worst war crimes that ever happened on this planet.

On a brighter note, the costumes and make up or whatever were pretty good, so 2 stars for that.
