'Piranha 3DD' is worse than predecessor 'Piranha 3D', yet I'd say it actually has moments that I'll somewhat remember (unlike the prior entry). There are three bits I minorly liked: Ving Rhames, David Hasselhoff and the David Koechner head gag.
That is literally it, though. It's a bad movie, no question. It even feels like a pale imitation of the previous flick, which is quite something given that 2010 release isn't even anything good itself. The humans in this are extremely dull, while the piranha barely registered to me whilst watching. At least the run time is short.
Danielle Panabaker is 'the best' cast member, aside from Rhames and Hasselhoff who steal the show with comparatively small roles. Adrian Martinez's character almost works, while I did like seeing Christopher Lloyd return. Interesting to see Matt Lintz, way before his role in 'The Walking Dead'.
Also, and I know I'm taking the lore of these things too seriously by saying this, but weren't the piranha supposed to be massive in this one; based on the end of the first film. This second movie ends with a tease of walking piranha, which is just as lousy an idea as the flying piranha from 'Piranha II: The Spawning'.
Thankfully, the aforementioned didn't happen as this didn't get a sequel. How long we giving it until someone somewhere decides to remake 'Piranha' for a third time? My money's on 2030.
