Wesley Stenzel’s review published on Letterboxd:
Popstar is tight, funny, efficient, and surprisingly well-structured upon rewatching. Not every joke hits it out of the park, but everything has a near-perfect setup, delivery, and conclusion. The Lonely Island guys give you just enough information and time to let everything about their surreal parody world sink in, and all the gags make total sense as a result. It’s a smartly-constructed dumb comedy.
