Well since most of you are seeing it now I guess I can go into a bit more depth than when I first reviewed it 2 weeks ago.
Biggest weakness in the film is the Earth stuff, as someone mentioned that second act felt really cheap. It probably had something to do with the setting, I think it would have been far better had that portion of the film been set in a city instead of small town USA, not only would Thor have to interact with a wider variety of human, but the stakes for genuine hurt to people in the final act would have increased dramatically. Really, no-one feels in any real danger. On top of that, Thor's change from arrogant God to humble one happens way too quickly, I don't buy it that someone can change overnight, it would have been better served if he actually spent some decent amount of time amongst humans, in different settings and locations, it actually could have been a grander story if he had to see what the world and humanity has to offer. It felt abridged for lack of better word.
I agree with this
Another plot issue I have is how Shield more or less just let Thor go, some dude breaks into a government facility and all it takes is a conjured up insanity story for him to be let go? That could have been handled way better.
I think they knew he was lying and let him go to see what was going on....thats why he had people following them
The character stuff was great and clearly the best part of the film, the scene with Thor and Loki when Thor is locked up is probably my favourite of the film, great acting and directing there. And Anthony Hopkins as Odin, probably my favourite character in the film, he genuinely feels like father figure, it could have been so easy for him to play up the role but he lends a gravitas and weight to the role, the moment he banished Thor there's real power in the acting, he is a god at that point. Brilliant.
The most obvious thing this film lacked was confidence, it took me a week or so to figure out what it was about it that felt off, and it was a lack in self belief. There's this sort of walking on eggs shells feeling about it, like they were too worried about not screwing up as opposed to simply giving it their all. I guess I can't blame them, the character could easily have turned out wrong, but at the same time the lack of ambition makes the experience feel far too vanilla in flavour. I guess the biggest complaint I have is that there really wasn't any chances taken, the film works fine, but it's not the type of film I felt I had to watch again immediately.
