“Big Top Evil” (*1/2 out of four) was a gory, one-note horror freak show about five delinquent youths (J. Larose, Austin Judd, and others) who embark on a road trip to locate the site of a mad slasher and instead end up lost and pursued by a group of cannibal clowns (led by Bill Moseley). Imagine Rob Zombie’s “The Devil Rejects” with no laughs but plenty of gore and crude humor (and clowns) and you’ve got an idea of what to expect here. Moseley seems to be more-or-less playing the same role he did in “The Texas Chainsaw Massacre 2” and he’s just as over-the-top and annoying.
