It wasn’t a bad movie, but it had problems.

The big problem, and this is pretty common with Marvel, was a weak villain. The Leader just wasn’t a big threat. He spent most of his time in the shadows. He got very little screen time. And his motivation was also really weak. He wanted a pardon… But he was also completely capable of starting world war 3, like that doesn’t make sense. Like an iron Man 3, The Mandarin started off the movie as an epic threat… Only to be revealed to be an actor and the actual bad guy was Killian… Who was an awful villain. But you don’t even have to have a villain that’s super strong or even has great motivation as long as they’re well written, like Mysterio. Red Hulk ends up being wasted on this movie, because they had no faith they could write something people would want to see, because post Thanos they’ve kind of been fumbling the ball. But I think they seem to forget is Thanos wasn’t there from the beginning they eventually led into him.

They either needed to really lean into The Leader, or Red Hulk. Not waste both on a 2 decade late Hulk sequel that doesn’t have Bruce or the Hulk.
