Barry Pepper, Susan Sarandon, and Dwayne Johnson in SnitchSNITCH

As a film star, Dwayne Johnson possesses a lot of gifts - or, at least, sufficiently impressive gifts for what his résumé has required. Though God knows he's physically intimidating, Johnson is also our most thoroughly genial of ass-kickers, with even his most violent of big-screen endeavors leavened by a welcome lightness of touch and hint of amused self-mockery. And as he has proved in all those bland family entertainments over the years, Johnson still manages to appear game and committed in movies that don't deserve his considerable charisma, often salvaging entire scenes through unexpectedly silly gestures or readings that show just how inventive a comedian he can be. (I was happy for 10 whole minutes following his brief channeling of co-star Michael Caine in Journey 2: The Mysterious Island. They were about the only 10 minutes during the movie in which I was happy.)

Ordinarily, Movie 43 would be the sort of unsatisfying, throwaway release that I'd dispense with in a paragraph, or maybe just a sentence or two. And it's not as though its opening-weekend box-office intake - a meager $5 million, despite the presence of nearly every star in Hollywood - necessitates longer consideration of the film. But this anthology comedy in the style of those '70s cult classics Kentucky Fried Movie and The Groove Tube seems to me a special case. How often, after all, do you get the chance to write about what might be your all-time least-enjoyable experience at the cineplex - including that time during the early '90s when you had to leave a screening for emergency root-canal surgery?
