The second feature by Toronto’s Rob Stefaniuk guns hard for instant-cult-classic status with its array of rocker cameos (e.g., Alice, Rollins, Iggy) and tale of a no-hoper band who start to get ahead when the members start growing fangs. But when a rock ’n’ roll horror comedy musical has so few laughs, a minimum of gore and such unremarkable songs, it’s hard not to feel that Suck is not what it oughta be. The satirical potshots at the music biz and the nondescript alt-rock tracks by the fictional band — with Stefaniuk as conflicted frontman and a fun Jessica Paré as the newly immortal bassist — feel a decade out of date and there’s way too little of the fun and fury found in like-minded efforts like Brothers of the Head and Hedwig and the Angry Inch.
