They may have gone too far in Ragnarok for my tastes. Avengers: Infinity War I think was a better balance throughout. There were times where it was just a little forced, and Thor has been funny prior to this, but in a Thor-like way. That's what made it funny. I don't think he needs to become so human that you don't get the Asgard difference.

He can be hurt. He can feel loss and pain. He can be thwarted. He can lose. His total lack of words at the end after basically having the chance to defeat Thanos and failing is something I hope they build on, that it just wasn't secondary. He couldn't answer when he was asked what happened, and he wasn't even in the foreground when Captain America realizes what's happened.
