“Warning: this film contains flashing images.” That disclaimer tells one truth and one lie. The truth: the music video for M.I.A.’s all-acronym-everything “Y.A.L.A.” should not be watched by anyone who regularly suffers from seizures. It’s Kanye’s “All of the Lights,” but literally all of the lights. The lie: music videos are not films. No, that would be disservice to ACTUAL classic films, like Billy Madison. “Y.A.L.A.” is no Billy Madison.
