Wow the Russos actually did it. I can't believe this movie works as well as it does. The movie just breezed by, there is so much going on and it is paced so well. The action is great and the stakes are real. Thanos's plan is a dumb one but they do make him a well rounded character and he is one of the few villains to actually pull it off. There is a ton of humor but it also manages to be really emotional at times. It is going to be a long year but at least we get to see Captain Marvel in between.

EDIT: After seeing it again it still is amazing how well everything works. This is probably the darkest MCU movie so far but still is fun and has a ton of one liners. The humor is still fantastic and on GotG level. I just realized that it is the original Avengers team that is left to start Avengers 4. I expect most everyone that turned to ash to come back but not without sacrificing the original team.
