An unintentionally funny fanzine-flavored documentary about They Might Be Giants, the indie-rock duo that has spent 20 years flitting along the line between the cult and the mainstream. The two bandmates, John Flansburgh and John Linnell, are Ur-ironic geeks who springboarded off the faux-naif ditty rock of Jonathan Richman to do some infectious ditties of their own. That's neither a small accomplishment nor, perhaps, a major one, but if you thought that the party-down metalheads in The Decline of Western Civilization II were full of themselves, just wait until you enter the echo chamber of whimsical egomania that is alt-rock attitude.
