Katy told me Jack Black was in a depression after this movie failed, so I felt bad for skipping it and thought I’d rent it to cheer the guy up. Maybe it’s director Liam Lynch who’s in a depression… if your feature debut bombs, do you get a second chance? I hope he’s at least working on a second album (and more music videos).

The celeb cameos are as good as you could hope for – meaning the film isn’t weighed down by the awkward injection of whichever actors would say yes, but they actually have funny parts that work with the movie. Amy Poehler as a waitress: (“do we have to pay for all these refills?”, “No, you’re so pretty you get everything for free.”), Neil Hamburger gets about one line, Dave Grohl was apparently the devil, Tim Robbins is surprisingly good at silly comedy under lots of makeup – only Ben Stiller is a problem as a prophetic Guitar Center employee, and even that is only because his scene goes on too long.

After an outstanding musical intro (a kid who is perfect as a young Jack Black with Meat Loaf as his metal-disapproving father), the D members meet and perform open mic nights, but in order to win the big open-mic grand prize they’ll need the titular pick made from satan’s horn. It’s a mix of some original episodes (biggest fan Lee is in the movie; they borrow then trash his car) and music videos (the final scene is basically the “Tribute” video with a less catchy song, and there’s a hilarious shroomy Sasquatch sequence). Kept me entertained.
