“Popstar: Never Stop Never Stopping,” the Lonely Island’s mockumentary styled after self-aggrandizing docs like Bieber’s “Never Say Never,” doesn’t often reach the kind of pitch that will shatter glass. It comes closest when its “Behind the Music” format dissolves and, before you know it, there’s (the film’s producer) Judd Apatow’s penis (definitely not in a box) smeared against a limousine window or Will Arnett’s recurring, cackling, beverage-wielding impression of TMZ’s Harvey Levin.

Gosling and Crowe do have chemistry, and an obvious sense of humor which gets them far. They’d have gotten farther, though, if the movie, while at times hilarious, didn’t have such an uneven feel, particularly a nasty edge that simply clashes with the desired jocular tone. Yes, there’s such a thing as dark comedy, but this is a comedy that occasionally just makes you feel queasy. There were moments I knew I was supposed to be laughing but found myself scribbling in my notes: “hmm, funny but not?”
