What I'm surprised about is that critically this movie is not doing as well as previous movies. It's at 84%, which is good, but a lot of the fresh reviews are pretty mixed. I really liked this movie a lot more than some of the better reviewed Marvel films.
As someone with a big comic book background, including having read the many infinity wars comics, I wonder if this movie is harder for casual fans to appreciate. Did anyone go with a non-comic book fan that had trouble watching the movie?
Anyways, I really liked the depiction of Thanos, although slightly different from the comic book. They obviously had to change things without the motivating factor of lady death. I also don't think I saw Thanos grin once. He was more of the cold calculating Titan than the mad Titan.
