Agree about Ghostbusters. Disagree here. Thor’s interplay with all the myriad characters is the key to the success of Ragnarok, I’d say. Much of the humor was scripted, but quite a lot was improv. The scripted Asgard scene with the play cracks me up every time, and I’ve watched it at least ten times. The history of this character is filled with bizarre moments, like when Thor was a frog, for god sakes. Best to deploy self-deprecating humor, whilst remaining true to that history.
