I have to agree with Bubonic. This game just plain sucks. There are moments of fun and greatness, but those are very few and far between. Basically, the entire point of the game is: travel to a new realm, fight hordes of enemies, look for power up icons, light up a bunch of ruins, defeat the boss, move on.
The problem I have, is that Thor never really feels all that powerful in this game. They either severely powered him down, or made the enemies ridiculously powerful, either way, it doesn't work. He's supposed to be a God, one smack from Mjolnir should take out almost any smaller enemy, instead, you'll knock them down repeatedly, only for them to get back up. It's ridiculous.
I wanted to like this game, I really, really did. The movie was incredible, and I was very excited to finally be able to control Thor in his own video game, but this is not Thor. This is a severely watered down, and rushed version of him. The "cut scenes" (if you want to call them that) are a joke, the voice acting is sub par (come on Hemsworth, you couldn't have put more into the "for Asgard!"?), and the combat is overly repetitive.
I would save your money until this goes in the discount bins. I'm trading it in today for something else. It's really not even worth finishing - and I'm on the last level.
