Thor 2 had a bit more charm and didn't take itself so seriously, which i consider a positive. Hemsworth and Hiddleston were again fantastic. I liked their relationship. I also really liked Frigga and Loki's relationship, even if it was only shown briefly, it was effective and i truly believed that Loki loved her and her death spurred him on. Her funeral was stunning. Visually it was also really good. The attack on Asgard and the escape from Asgard were awesome. I also liked the finale and the way the worm holes were used in the fight. Like MoS it had fantastic production design. Asgard looked fantastic. Malekith was a weak villain though. Eccleston was wasted. Hopkins totally phoned it in as Odin. A lot of the comedy fell flat, although the scene where Selvig is explaining his theories then it's shown he is in a nut house really made me laugh.
Overall, they are about even for me. I enjoy them both, but was also disappointed in some ways. 7/10.
