Finally, toward the end of “Zoolander 2” (2016), I laughed out loud. I don’t know whether it was that particular gag or just the absurdity of the whole thing that finally got to me. This movie is stupid. It knows it’s stupid. It knows that you know it’s stupid. It wasn’t trying not to be stupid. In fact, because it knows that you know it’s stupid, it doubled down on stupid until stupid became absurd and I laughed out loud. Just like the original, there’s dopey male models and world-saving hijinks. Thank god Penelope Cruz has a sense of humor.
