In my house we have something called "Crappy Movie Night" This movie was everything we hoped for. * Spoiler Alert * The fish were created to benefit mankind (in a way that is never explained). But they escape - no thanks to an army colonel who appears to be the leader of Venezuela and whose men only seem to know one word of spanish (vamanos).They try to blow them up, but they eat the battleship. Then try to nuke them, but that didn't work. So, in the end, they decide to go after them using spear guns. The piranhas attack Key West by jumping into the roof of buildings and (for some unknown reason) exploding. The actor who played Greg Brady is playing Bob Grady. His main concern... "How long will it take them to reach Washington DC?" And the movie ends with everyone patting themselves on the back because they managed to kill exactly one piranha. Presumably the other fish were so discouraged by this devastating loss they decided to self-destruct, but we'll never know.
Is this movie good? Well, with a title like Mega Piranha you should already know what to expect. However, that doesn't mean that the movie isn't enjoyable which it certainly is. So kick back, relax, grab a cold one and have a fun time watching this neat little flick if you decide to rent it.
