Thor: The Dark World is a fascinating movie that is definitely more complicated than previous Marvel movies and also more violent, though not as much as Iron Man 3. Parents should know that in this film there is a bit of drinking, including a woman asking a man to 'have a drink with her' though it is on Asgard and therefore a bit different than on earth. Eric Selvig is shown naked on TV with parts blurred out. The violence is mostly super hero violence, though the amount of dead bodies shown on screen is high. There is little blood in comparison to an average fighting movie but for Marvel there is a decent amount. There is a lot of fighting, several people are stabbed, a character's hand is cut off, and two supporting characters are both brutally killed by having a sword run through them. (one is a woman). The language is nothing that a 13 year old can't handle, with the worst being s**t. As for a "scary" factor, the villain himself is none too terrifying but his henchmen's appearance might be frightening to younger children, and the powerful destructive force that possesses Jane also might be scary due to the changes that her eyes sometimes go through. Characters include Thor, of course, who is more responsible than the previous movie but still commits high treason against Odin. He is a strong lead however and there's nothing to complain about from him. Jane gets more screen time but still doesn't seem to be able to do anything for herself - the most fighting she ever does is slap Thor twice and Loki once, all the while letting Frigg, Thor, Loki and Sif do all the fighting for her. She is much a damsel in distress but we love her anyway. Speaking of Loki, Tom Hiddleston really steals the show. Loki seems to have developed a sense of humor in prison and provides comic relief as well as pulling profound senses of pity from us in certain scenes. It is still up for grabs whether or not he is a 'good guy' since he seems to be constantly helping and then backstabbing but then helping again (and it is shown that he really loved at least one member of his family), but we definitely do get to see more of Loki's good side and less of his evil. The main villain is completely unmemorable to the point that I can't even remember his name though he is acted well. He is cruel and typical in his plots, though he doesn't monologue which is a relief. Darcy returns and provides a bit of humor though she is mostly annoying. Odin is a bit weak but then Anthony Hopkins is getting old. Overall it is a good movie, with good characters and role models and messages, that I would buy so as to be able to watch again but not for younger children, and it is probably better to go into it with the mindset that the main plot line is cliche and it is the sub plots that make it worthwhile.
