The film’s name is creative, and it features a David Hasselhoff appearance, along with a scene where Josh removes his own penis. _Piranha 3DD_ really commits to the silliness of the series. If they had managed to add more laughs alongside that, it could have been something special; however, as it stands, it’s mostly just mindless. It's not bad if you enjoy this type of movie, but it doesn't quite measure up even to the earlier film. _Final rating:★★ - There were elements I liked, but ultimately it didn't come together well._
