That is not to say that it doesn't have its faults. There are a few places where the CGI and the green screen (such as some of the scenes "in Norway") are off enough to remove me from the movie for a bit. Also, there are several times that I questioned the logic behind the other worlds that we see. In particular, I have a number of questions about the Asgardians themselves. However, my largest concern comes from the movie's biggest selling point: its humor. It was sometimes jarring for me to see what other movies would treat as tragic (such as the fate of the Warriors Three) or even horrific events almost completely disregarded by the time the next joke is made, and those jokes come at a rapid pace.
That said, it is a tremendously funny movie. Everyone in the audience was laughing through most of the movie to the point that I know I need to see it to catch anything I might have forgotten or missed. The action is amazing, yet still possible to follow. As others have said, it felt like all of the best parts of the action cartoons I watched growing up taken to the next level and put into a overall story that stays internally consistent while still being exciting and fun.
All of the actors did a tremendous job building up their characters. Karl Urban and Idris Elba did not have enough screen time, yet still brought depth to their characters. Cate Blanchett and Jeff Goldblum were pure gold in their performances as the main villains. Tom Hiddleston and Mark Ruffalo did a great job bringing back their characters of Loki and Hulk (respectively). Tessa Thompson as Valkyrie is a great replacement for both Sif and Jane Foster (played in previous movies by Jaimie Alexander and Natalie Portman). However, it is Chris Hemsworth who continually steals the show (as he should) making me like Thor better than I have in any of the previous movies.
I look forward to seeing it again.
