The dialogue is cringe-worthy, with characters spouting one-liners that are supposed to be witty but come off as ridiculous. The pacing is sluggish, with long stretches of boring exposition that make you wonder when the piranhas will finally start eating people.

Despite its many, many flaws, "Piranha 3D" has a certain inadvertent charm. It's a film that's so bad, it's become fascinating in its own right - a trainwreck that you can't look away from. If you're a fan of campy, over-the-top horror movies, you might find some guilty pleasure enjoyment here. Just don't say I didn't warn you...

The plot is predictably paper-thin: a school of piranhas, made hyper-aggressive by a freak storm and some wacky scientific mumbo-jumbo, start chomping on humans in a lakeside resort. The cast, featuring Elisabeth Shue and Adam Scott, sleepwalks through their roles, delivering wooden performances that make you cringe.

Watch "Piranha 3D" with a group of friends, make fun of its obvious flaws, and enjoy the so-bad-it's-good ride. Just don't expect a good film.

(for its inadvertent entertainment value)

I dove into the depths of "Piranha 3D" on Dailymotion, expecting a cheesy B-movie with some mindless fun. What I got was a film that's so bad, it's almost... endearing?
