with 2023’s The Toxic Avenger, Blair is back at Sundance with another curious, tonally erratic thriller-comedy, The Shitheads. He’s been assigned a new partner, Mark, a drug-addled slacker played with antic energy by Dave Franco. The Shitheads The Bottom Line A movie that’s way better than its first impression. Blair seems to be setting up an awfully familiar plot, or a combination of hoary tropes: the zany road trip and the guy-saddled-with-an-unruly-kid story. Jackson and Franco settle into their performances (Jackson is especially nuanced and surprising), just as Sheridan is revealed to be a far tricksier, more complicated, more dangerous figure than initially assumed.
