Unfortunately for me, this one had so many things one's mind could just not let go off: you spend half of the movie sincerely disliking the main character. The jury is still out whether it is because of Thor himself or because of the actor who plays him (Chris Hemsworth).
It is always depressing to see Anthony Hopkins in roles that are sidelined and borderline trashy (think The Rite), as is the case with this one. Ray Stevenson, my Titus Pullo, has most definately been thrown into the minor roles that assault his acting abilities and make me flabergasted but I can live with that - albeit with some pain. What I can't understand is the role of Natalie Portman as the love interest. I mean, what in Valhalla's name is she even doing in this movie?! It seems as if every second film has Natalie Portman in it. Come on!
Kenneth Branagh really, really, really should not have fucked this up - dialogues are childish, script is purposeless (there is no storyline there, no continuity, no building up to or resolving of something) but there sure is a "let's make a sequel and announce the Avengers" in the form of Samuel L. Jackson at the end-credits. Kenneth, honey, if you can make good Shakespeare movies why was it so hard to make a decent Hollywood one?
I have to admit, though, that one thing they did do perfectly: piss on everything that Marvel's Thor represents.
Imdb has it as a 7.6 - whaaaat?! It's a 5 and that's stretching it too far.
