Why is this happening to Piranha? Wasn't the first one successful?
Because the result of the sequel is said to be abysmal, they try to do damage control by cutting down the number of theaters. They shouldn't replace Aja (director of the first one) at the first place.
I know right? All those dumb characters have to do is stay out of the water, and their problem is solved.
A lot of the characters, in Piranha 3D, died out of water, you have to see the first one to understand why staying out of the water is not the simple solution.
