To me the movie wasn't that bad as compared to Thor: Love and thunder and Ant man and the wasp 3. In fact, this movie is going to play crucial part in upcoming marvel movies. Some of the characters like Nick Fury and Captain Marvel too were somewhere off to their usual character.
Also, I wanna mention Park seo joon (prince Yan), he is one of my favorite actors and he is actually a great actor but the script didn't did justice to him. Although his part was small but it could've been presented in a better way.
But I don't think it deserves that much hate, marvel could've done a better job but it wasn't worse. So, if you wanna watch it go ahead after all it's only 1h 45m.
