Just finish watching Piranha and find it indeed entertaining and disgusted. If you like to watch SAW, you will definitely like Piranha. It is about human behaviour that leads to death. It is also about these monster fish that eats human meat. The person that introduces me this movie told me to look out for the blood, and I am really have to say I am impress with the way they made the blood to be so realistic. The shocking moment I guess is at the last part where I see Piranha mother.
