How bad is it? It's a comedy with zero laughs. Zero.
Should you see it? NO.
Quentin Tarantino films seem like a good subject for satire, but this fails on every level. Not able to stick with a parody of Pulp Fiction, this goes on to Reservoir Dogs, which is fine, and then to Natural Born Killers (which would've been a good target by itself) and then to Forrest Gump and Nell and Clerks and Reality Bites and... somebody make it stop! The cast is interesting; though top-billed is Tommy Davidson, who's been in several atrocities, there's Julie Brown, Sandra Bernhard, Colleen Camp, Dan Castellaneta, Tim Kazurinsky, Kevin Meaney, Jennifer Coolidge, Judy Tenuta, Jimmie Walker, Simbi Khali and a host of others and, despite a flicker of wit and a couple decent impersonations, none of them are good. I could discuss why it doesn't work, but it isn't worth the effort. Avoid at all costs.
