On the on the one hand, saying Thunderbolts* is my favorite Marvel flick to date is a bit like saying crabs are my favorite arthropod because, well, you know, cockroaches are my least favorite arthropod—so the comparison is a bit problematic, to say the least.
But on the other hand, Thunderbolts* is actually quite adorable. Florence Pugh's comedic timing is right up there with Julia Louis-Dreyfus's (and David Harbour consistently brings a smile to my face), so that's saying something.
And if I had a third hand, it would hold the fact that Thunderbolts* explores more worthwhile topics (like depression, isolation, loneliness, and repressed trauma) than others in Marvel's canon. But that ain't saying much either.
So I'll put it this way, sans all the relativity: Thunderbolts* is funny, deep-ish, and entertaining. Taken together, all three traits make it worth the time.
If you haven't seen it yet, you should. It's good fare, despite 40% of the cast being nepo-babies!
