Piranha 3DD. Irritatingly bad, an a massive let-down from the first one. While that movie was actually a pretty good movie wrapped up with some outstanding gore effects, this one just felt really cheap and lazy. The acting was embarrassing, the flow was really awkward (stupid situation morphed into another stupid situation with no real thought between them), a lot of the jokes misfired, and the whole thing felt like some weird self-parody, which simply doesn't work at all. Things do pick up for the climax, especially once David Hasselhoff shows up (and Ving Rhames for... some reason), but for every gore bit or dark-humored joke that hits, another one still misfires. Ultimately it all is one you'll be laughing at a lot more than you'll be laughing with, and that fact that it's still kinda dull for a movie that's barely over 70 minutes (plus an extra 10 of "outtakes") does it no favors at all. It's certainly not outlandishly terrible (because for real, some stuff does actually hit the mark), it's just botched in a cheap and lazy fashion. Skip it and stick to the first one, that one's a good old gonzo masterpiece.
