Misconceived pairing of Adam Sandler and Jack Nicholson, but still curiously enjoyable and often funny. Sandler underplays (though not to the extent he did in Punch-Drunk Love) as a geek wrongly diagnosed with rage problems; Jack’s the quack assigned to set him straight. Comic twist being: Jack’s borderline deranged. While some scenes misfire, there’s usually a weird (intentional or not) tension between the two, each straining to pull off this unlikely marriage. They just about do.
