Could it be that the movie we ultimately got wasn't what Taika originally had in mind but the studio pushed for more shenanigans and silly/wacky Thor? I mean, I love silly/wacky Thor, but the way we saw him in Ragnarok and Endgame. This was a level beyond. Maybe Taika got pushed into this version? Or scenes making it more serious were cut in the end? It wouldn't be the first time Marvel changed what the director had in mind. Thor The Dark World comes to mind.
