I saw Piranhas 3D today. Don't know what to make if it. Is it a comedy or a horror? I think you have to watch these type of movies with an open mind ready to belive anything you see, otherwise you don't enjoy it nit-picking anything that may not be factual. Some very beautiful women in the film. A sustained piranha attack scene with some deaths that make you twitch a little. Either way, I don't think a sequel is needed.
I saw the trailer for that and thought 'eww where do they come up with this stuff'.
'The Human Centipede' is one film that has that same feel about it. Their is a link to the preview below.
