Mark Ruffalo thought the different direction of Thor and Hulk in Thor: Ragnarok would possibly break the Marvel Cinematic Universe.
The biggest difference, of course, was that the Guardians were their own entities, as opposed to Thor and Hulk, who were introduced in the MCU in a much different way.
It’s hard to say whether Waititi’s new direction actually helped Thor: Raganarok‘s bottom line, but it’s pretty safe to say it didn’t hurt.
