Every so often, a movie opens that you’re sure you and some friends plotted out on a bar napkin once upon a late night. You know that bigger-than-life picture: It’s the movie-I’ll-never-make fantasy, the get-rich-flick scheme that you are positive someone with money will eventually produce. Because someone with money is always making a movie like “Stuber,” an entertainment that is at once knowingly derivative (it’s like “Lethal Weapon”!) and somehow just different enough (with ride sharing!).

A breezily violent two-hander and a dubious feature-length commercial for Uber, “Stuber” is about two guys who meet cute, kill people and bond. It’s one of those dumb movies that are so gleeful about their own idiocy that taking it seriously may seem pointless, which is always a good reason to take a movie seriously. “Stuber” is certainly worth a thought or two for how it fits into the tradition of buddy action movies, those bromances with bullets that include “Butch Cassidy and the Sundance Kid,” “48 Hrs.,” “Bad Boys,” “Rush Hour,” “21 Jump Street” and so forth, ad infinitum.

While this subgenre has slightly changed over time — with somewhat diversified casting, as here — the focus on the preservation (veneration) of heterosexual male intimacy remains constant. That’s the case in “Stuber,” which centers on Stu (Kumail Nanjiani), a sweetly beleaguered Los Angeles Uber driver with an aspirational “ FIVESTAR ” vanity plate. One day, he picks up Vic (Dave Bautista), a police detective who, on the same day that he’s had eye surgery, gets a tip on a killer (Iko Uwais). Since Vic can’t drive, he summons an Uber, thus initiating the latest high-concept duet.
