After I watched "P", honesly, I felt sick to dead."Piranha" is a movie about a human tragedy suffered from a kind of fish, named "Piranha", which has been living in sea bolcano for nearly one million year. I think "Piranha" is belong to horror and comedy Genre. On one side, Horror is because the bloody bodies ate by the damn piranha. All the terrible shot is jumped cut scene by scene. On the other hand, the humorous element is much more from the piranha, which is they love targeting human's body except for the penis and the gels for the boom job.
In my point, I am not a big fan of "P" because of the old theme. Such as mass disaster, nature revenge,etc. As a audience, I was kinda fed up with those boring theme. However, at the end of the movie, there was a little bit out of my expectation. The whole group of survivors(main characters in "p") was saved on the boat.They both thougnt they were safe and killed all the piranha thoroughly. What in my mind was human can overcome the nature finally. Suddenly, the camera jumped cut to another scene, that is, the professor made a phone call to them and said "there is still tens of thousands piranha inside the deep sea. What you guys killed is just their babies." Then, one of survivors just was eaten by the parent piranha in the last high speed scene. Ahh, maybe by this movie, Alexandre Aja(director) tries to tell us, we should revere the nature.　
Anyway, 3D visual effection is awesome and I don't think I will go to have swimming in summer forever. - -
