I think Thor wasn't as good as it could be because Marvel movies typically screw up the villain and the most interesting thing about Thor is his villains.
When it comes to Marvel movies, I don't know what the
happened. The first Blade was great - Deacon Frost was a bad motherfucker (the Blade II villain wasn't too shabby either). But ever since then Marvel villiains have been fucking pussies. Doc Oc was cool but the rest of the Marvel villains can kiss my ass.
Bringing me to Loki. Marvel, what the
wtf wtf. This is your baddest villain and you castrate him, you turn him into a whiny emo bitch. Wahhh I'm not a real Asgardian. Wahhh I'm not your real son. This is the baddest of the badass trickster gods and you have turned him into a second rate Mordred.
Finally shame on Branagh. Branagh - you starred in Othello, you fucking played Iago! Iago! I mean - you can't get any closer to what Loki should be. And then Branagh directs Thor and we get some half-ass scifi romeo and juliet. Way to sellout.
Thor was not a bad movie, but it was kinda pointless.
