The biggest problem with The Dark World is that it services Loki better than it does Thor. As a result, Thor, is one of the movie’s least interesting characters. He’s trumped only by Malekith — Marvel’s dullest villain ever — in his inability to make the audience care about his needs and wants.
Still, Tom Hiddleston is completely dialed in here as Loki and is easily the most engaging character of the bunch. The production design is great and the Asgardian world building is cool. There are also some awesome and inventive action sequences. It’s just too bad that Thor the character gets lost along the way. Thankfully, that all changed with Ragnarok.
