Piranha (2010)

Look, the long and short of this--if you pardon the pun--is that with quotes like "they took my penis", floating silicon from torn apart bodies and floating digital penises, this movie is excessive horror mixed with copious amounts of nudity, often combining both in a surprisingly distrubing way.

Further, watching the 2D version of this showed just how focused on the 3D they were, in that a significant portion of the films elements were clearly digital, and clearly designed to "pop out at you" in 3D.

Red Riding Hood (2011)

My 1st failure: anticipating a horror flick.

My 2nd failure: anticipating the typical horror flick formula... you know, half-naked women running around scared of the evil monster.

Instead, we take The Village--a superb film--and Twilight--sparkly vampires???--and we mash them together with a lower budget and a crappy performance from Gary Oldman. Even the love interest was subpar, but hey Amanda looks amazing.
