I can't even call this a movie, it's more like a massive porno with some fish thrown in. The plot is decent, I mean you can't go wrong with swarms of killer fish. But no, these are apparently prehistoric fish that somehow managed to survive with no food for millions of years in a cave. Okay? Well anyways, you can't go 10 minutes without seeing boobs, a butt, or someone doing something sexual. I realize this seems to be the staple for the newer low budget monster flicks like this, but give it a break. They also go WAAAAAY too far with the gore, and I mean they use an unnecessary amount of blood and carnage to shock audiences. If you're one of those people who feed off that kind a thing, then this is a movie for you. If you want something that's actually...ya know, good, it's not gonna be for you.

Had potential, but ends up as another common-or-garden creature-horror movie. Plot is predictable and formulaic - pretty much Jaws In A Lake, and a b-grade attempt at that. Direction is paint-by-numbers. Most amazingly for a 3-D movie, the CGI isn't that great.Acting is so-so. Elizabeth Shue does her best with a dud script. Steven McQueen is one-dimensional. Jerry O'Connell only ever had one dimension to his acting. Ving Rhames has never had any pretense to be anything more than an action actor, and does that role well here.Jessica Szohr is good in her role, and Kelly Brook (and dozens of other girls) provide the eye candy.Brief cameo from Richard Dreyfuss, in a clear link and homage to Jaws. Christopher Lloyd does one of his usual over-the-top insane performances.Could have been a new and innovative take on a genre, but wasn't.

This is an awful awful movie. Do not see it. The story line is awful. The ending is awful. It is not scary at all. Just unbelievable gross. I can't not believe it got a 5.5. That is just overrating it. It is not a remake of the classic horror masterpiece Piranha (1978). The only thing this movie has in come with Piranha (1978) is there are both about the same kind of monster. Other then that it is like saying Interview with a vampire is a remake of Dracula. Do not waste your time. Do not waste your money. Do not see this awful movie. Good actors wasted there talent being in this awful movie. The special effects crew did a great job. I can not believe that same man who wrote Sorority Row wrote this crap. He can do a good job if he wants to. This a great movie to skip. Do not see it.

"Matt Boyd" (Richard Dreyfuss) is out fishing on Lake Victoria when an earthquake hits and opens up an underground lake directly under his boat. Not only does he become trapped by a sudden whirlpool but the fissure also allows thousands of prehistoric piranha to escape from their subterranean prison into Lake Victoria. And they are very hungry. To make matters even worse there is an annual holiday taking place at the lake during this same time and this special event typically hosts over 50,000 college students from all over. Now rather than reveal any more of this movie I will just say that it featured two good actors in Elisabeth Shue (as "Sheriff Julie Forester") and Ving Rhames ("Deputy Fallon") along with several attractive young actresses in Jessica Szohr ("Kelly"), Kelly Brook ("Danni") and Riley Steele ("Crystal"). Unfortunately, rather than concentrating solely on these fine people--and possibly giving both Elisabeth Shue and Ving Rhames roles befitting their abilities--the director (Alexandre Aja) chose to spend an inordinate amount of time focusing on some of the dorkiest men ever caught on camera. Likewise, the music chosen for the multitude of party scenes was equally bad as well. Additionally, one particular scene, which was supposed to be humorous, ended up being just plain silly and vulgar. As a result, although the director had the necessary ingredients for a pretty good movie, he obviously wasn't up to the task and this movie simply proves that point. Slightly below average.
