Generally liked this season - the finale wasn’t the best (even if all the cosmic fights were fun) but it had a couple of the best episodes of the whole series.
Agatha in Hollywood was wall-to-wall superb and really made me root for Agatha - up against the impersonal power of the Celestials she was just the ticket.
And as noted above, Alexei and Bucky were a buddy movie for the ages. Alexei is such an amazing character in this version and their chemistry was superb. This episode had some of the most PC dialogue ever:
Bucky: I think I murdered that guy. Sorry.
Alexei: Well, he was not very nice guy.
