10. Piranha 3DD
Director: John Gulager
Stars: Danielle Panabaker, Matt Bush, David Koechner, Chris Zylka, Katrina Bowden, Gary Busey, David Hasselhoff, Christopher Lloyd
A tongue-in-cheek horror-comedy with the sexy Danielle Panabaker, an appropriately crazy Gary Busey, a copious amount of fake boobies bouncing in three-dimensions, and hundreds of killer fish? You'd think that the unnecessary but, at one point, welcome sequel Piranha 3DD would've been a no-brainer for fans of dumb but fun genre exercises. But you'd be horribly wrong.
Without a single funny joke or an ounce of witty intelligence, this abject failure drowns in stupidity and overboard gratuitousness. It's as if the filmmakers knew their talents were on autopilot and lazily kept adding more breasts and blood, instead of any of the first Piranha 3D's excitement and perverse cleverness. Calling Piranha 3DD a wannabe SyFy network movie would be an insult to the almighty Megashark.
