No, he’s been big wasted. I know you don’t particularly care for his character much and that’s okay but I think almost everyone can admit his story has been really hit or miss in the MCU. The first movie set up great stuff, the recast obviously is odd and seeing Ed Norton as him is jarring but it had huge potential. But yet, after that, you didn’t see Betty Ross, Blonsky or even Ross after Banner again. Almost none of Bruce Banner’s side of the MCU was shown again. Obviously that will change with She Hulk but it made Banner’s character arc very lifeless.
Banner was amazing in Avengers 1 and Age Of Ultron imo, the one Avenger that was the loose cannon, always on edge and weary of everything. Joss Whedon, yes, I know, did do Banner right
Taika Waititi obviously is much better but even then, he was really off character in Ragnarok and we all know the situation with IW and Endgame. The Russos screwed Hulk and Banner forever. Overall, Banner has been given the short stick, sadly. I just hope after She Hulk, he gets the justice he deserves. Hopefully, you guys see where I’m coming from, as such a huge Hulk fan.
