The movie felt like A LOT was left on the cutting room floor. It was a real short film. I think it could have easily benefited from an extra 20/25 minutes. I LOVED the first Thor film, I loved Chris Hemsworth, I loved his chemistry with Portman, I loved the cinematography, everything about it just hit the right notes for me. When Thor TDW came out it looked SO epic and I was really excited to see Jane Foster go to Thor's world where it would be her turn to be the fish out of water AND it would give us the chance to see more of Asgard and Thor's way of life. There was SO much potential to explore all that but the movie just rushed through everything and didn't give anything a chance to breathe and in the end we didn't get to see that much more of Asgard than the first film.
All in all, I still thought TDW was a good film. I actually liked Maleketh alot and thought he was by far the most formidable villain in the MCU thus far. He just wasn't given enough depth. I think more exploration of Maleketh and maybe 10/15 more minutes of Jane getting to know Thor's world: his friends, his family, his locations....all of that would have GREATLY enhanced the film. The movie felt too much like an "episode" and not a full "film."
