Saw it this afternoon.
These actors work really well together. Sometimes you watch something and people are trying really hard to say their lines the right way, but they don't have any chemistry - these guys are a great mix. And David Harbour must have so much fun playing Red Guardian.
Fun action scenes. Some other scenes that were actually really touching.
Edited, because I forgot one thing - it felt a little more like an older Marvel movie, pre-Infinity War/pre-Endgame. There was a good story, but there was also some good world-building on what has happened before and some setup for what could happen next.
I have some "what are they going to do with that?" questions, but I'll wait until more people watch it and jump in on the discussion.
