I loved this movie, and I think it's great for ages 10+.
Consumerism isn't that apparent, with product placement for a cereal and some things in the background. Thor is part of Marvel's movie arc, so of course they're going to mention Iron Man. Two other Marvel characters also make an appearance.
The battle scenes weren't bloody at all, but could be intense for younger kids. One family did have to take their child out of the theater - the kid looked to be about 5. If your kid gets scared easy by monsters or battle scenes, don't see this.
That being said, the role models were great - Jane, the scientist, won't back down on her beliefs and is strong in her convictions; Odin, Thor's father, is a just ruler, who wants peace for his realm and wants Thor to be the best ruler he can be. Thor starts off the movie as an arrogant prince, akin to the star football player of Asgard. Through the movie he learns to be selfless and wise.
There's only one scene where drinking is prevalent (it's only on the side in the Asgard scenes) and a scientist is shown drunk, with Thor having to carry him back to his house.
There were only minor curse words, and nothing big like the S or F words.
There was one long kiss and comments on Thor's physique.
It's a great movie, and was amazing in 3D. If you plan on seeing any of the other movies Marvel Studios is putting out within the next couple of years (Captain America; Avengers; etc) stay after the credits for Thor!
