I like it.
I really don't know what they were trying to do with Hulk. He was terrible in both films. Killed all excitement I had for the character.
He has another movie on the books breh, Endgame is setting up Bruce for a heel turn.
He discovered time travel and divergent timelines, figured out how to merge his personalities but he is CLEARLY repressing his anger. He's obviously not done tinkering with his machine and he won't be content with his arm without trying to fix it. His rage can't stay repressed forever and when it does resurface...it'll be in the hands of someone with a sharp intellect. The natural progression from Professor Hulk will be Maestro.
