I agree with the majority of what you said, especially about Whedon and a lot of what you liked.

And I feel like them feeling like a team hasn't come yet, possibly on purpose. I think it sets the characters and dynamics to be developed and explored in the coming solo movies and that by the next time they do a huge group movie, everything will be solid because everyone will have worked together more by then.

I'm glad to know your thoughts and that you're gonna watch the next movies set up!
