Straight-forward, fun, forgivably excessive. Matilda Lutz shines, but all four performances are very good, and bolster an otherwise fairly minimal script. Starts out on a tense, disconcerting note and gradually develops its own brand of outrageousness in a (mostly) fun way.
There is one absolutely appalling shot in this movie involving an iguana that took me a while to recover from, but beyond that I have no real complaints. An exciting debut, slickly shot and well edited, successfully evoking old-school trash cinema with humor and style.
