Our Idiot Brother is not a great Paul Rudd movie, like Wet Hot American Summer or Role Models. Instead, it’s a good movie that probably would’ve sucked had Rudd not brought his particular brand of brilliance to the proceedings. Rudd shines as stoner-simpleton Ned, who is briefly imprisoned at the beginning of the film after trying to sell pot to a uniformed police officer. When Ned goes to live with his sisters (played by Elizabeth Banks, Zooey Deschanel and Emily Mortimer), the movie loses a little steam, yet Rudd always manages to snap it back to life with his charms. T.J. Miller steals scenes as Billy, the stoned biodynamic farmer who shacks up with Ned’s girlfriend (the talented Kathryn Hahn, as funny here as she was in Step Brothers) while he’s in custody.
