First off, let me say that I am a big fan of not only the original PIRANHA movie from 1978 but also the 2010 remake. The 2010 version has a lot going for it including a likeable cast, over the top gore effects and some pretty cool 3D. Unfortunately the sequel offers none of this.
I remember, months back, seeing the trailer for this movie and rolling my eyes in disgust. To me it represented the marriage between two highly annoying Hollywood trends; 1) remaking older movies and 2) presenting them in 3D whether the added effects were warranted or not. After picking up the latest issue of Rue Morgue, however, I changed my mind. They did a retrospective piece on the original PIRANHA as well as an article featuring the new one. Needless to say, I was hooked (no pun intended).
