The She-Hulk comic book is comedy. It’s a lot about the joke that they had to make a women version of Hulk and it leans into being campy and fun. Sure she does super hero stuff, but it’s not “serious”

The show took that to be sorta sitcom-like comedy breaking the 4th wall to act as the camp. Because that’s actually the character in the comic too. She’s more Deadpool than Hulk and makes jokes about the situation to the reader
