I'm meh about this. This is giving Spider-Man: Ragnarok. I guess Hulk is on the loose again and has to fight another superhero and Spider-Man needs to headline with another Marvel superhero like in the previous 3 films. Been there, done that.

I'll say what I said before...I'm fine with Bruce Banner so long as he's doing new things. Regurgitating the past Hulk vs. hero (in this case Spider-Man) fights I'm against and have no interest in at all, even less so in a Spider-Man movie - that is emphasis and fight time they could have given to an actual Spidey villain.

If there’s a Hulk fight again, Hulk could be just infected by the symbiote (left at the end of No Way Home) or Mr. Negative’s influence or something like that and it’s just a small part of the movie…retreading Thor Ragnarok. And Age of Ultron. And whatever I’m forgetting. Blah.

I just think its redundant to have Hulk in this. Its really unfortunate Marvel Studios cannot do another Hulk movie (even if they wanted to, that would have been successful post-Avengers 2012 and there should have been a Hulk trilogy by now), so they have to relegate the Hulk in supporting role/2nd lead in solo projects of other Marvel heroes.
