The B-Team*
*(Not the real Avengers)
So about that asterisk in the title-- (skip this one paragraph if you haven't seen the picture!) turns out it's exactly what it signifies, a mark meant to refer to a footnote or omitted matter, in this case the movie's real name The New Avengers, suggesting several things: 1) this is about the level of humor we're getting here on out, more meta and complicated and not that much funnier, and 2) this movie and the characters in it are placeholders for when the real thing arrives.
Which is both unfair and totally appropriate. Thunderbolts* takes the classic premise of misfits so misbegotten they can't possibly work together and somehow contrive that they not only do so but also win the day: think the original The Avengers (2012), or (off the top of my head) Stripes (1981), or before that and without superpowers (or even military hardware) The Bad News Bears (1976); think all the way back to one of the earliest misfit teams ever assembled for impossible missions, Akira Kurosawa's 1954 Seven Samurai, with Florence Pugh in the Kambei Shimada role of putative leader and David Harbour in the Kikuchiyo role of big-hearted comic relief.
