The concept behind Spinal Tap seemed like it would be hilarious, and there are several moments here that appear amusing in principle. However, ideas themselves aren't inherently humorous. What made the first film so exceptional was the scene involving the bassist’s cucumber wrapped in foil being taken away. This one’s standout moment is a reference to the only Black performer in the movie. Does the idea of women assuming roles typically held by men strike you as funny? Consider this—a female drummer! Hold on... LESBIAN! It feels like they brought in someone who writes for Aubrey Plaza's projects.
