This Netflix movie got an intriguing review from Peter Suderman at Reason, so (as they say) why not? It is genre-icized at IMDB as "Action, Comedy, Crime", but I'd add the caveat that the comedy is pretty dark.
Glen Powell plays Gary Johnson, an affable instructor at the local college. But he moonlights as the technical guy for a small squad of cops with a unique specialty: one of them poses as a hired assassin, then when money changes hands, the team swoops in to arrest the "customer".
Apparently it's illegal to even hire a hit man, even a pretend one. Go figure.
Anyway, one day an unexpected emergency occurs, and Gary is enlisted to play the fake hit man. It turns out he's good at it! So good that he becomes the regular fake, and the previous one gets relegated to backup status. Causing some hard feelings.
Further complication: one customer turns out to be a beautiful woman, Madison. And while discussing things with Gary, she displays ambivalence. Gary talks her out of the deal, but… oops, it seems he's got himself romantically involved. And then things get really complicated. It's a screwball comedy, except with killing.
For a slightly more sophisticated analysis of what's going on, see the Suderman review linked above. I have to admit being disappointed in the ending.
