Dynamixor The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

ActuallyGlimmer The best films of this genre always show a path and provide a takeaway for being a better person.

Robert Joyner The plot isn't so bad, but the pace of storytelling is too slow which makes people bored. Certain moments are so obvious and unnecessary for the main plot. I would've fast-forwarded those moments if it was an online streaming. The ending looks like implying a sequel, not sure if this movie will get one

Deanna There are moments in this movie where the great movie it could've been peek out... They're fleeting, here, but they're worth savoring, and they happen often enough to make it worth your while.

Julian R. White 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.

grantss 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.

Ilikehorrormovies I don't know what I'm watching! Am I watching a porno or a horror movie? This movie doesn't make sense at all like the cgi is terrible like it look unfinished. I think it's a B movie so I don't know. What a awful story it is. This movie is a porno but with no sex. One thing I got to say is, it's gory as hell but it doesn't scare me at all. This movie has 3-D but it's cheesy so I'm not falling for that. Man, Netflix starting to has crappy movies now.

vonhelvete Piranha 3D isn't a good movie! It's filled with bad effects, worse acting and a really dumb plot. All this makes this tasteless flick so good! It's filled with all the crappy stuff you need to get a good laugh and at the same time a "what the hell did I just watch"-feeling. LOADS of blood, extremely ugly blood-thirsty fish and sexy women, all in a crazy vortex of entrails, screaming and hilarious one liners. A really stupid flick I can't help to love!
