I saw Pirhana 3DD last night. I never got a chance to see the previous one.
It sort of reminded me of Final Destination 4 with them at the pool. I couldn't believe Danielle Panabaker was in it, I really liked her in the Friday 13th remake. I found it really funny at parts, there was one big jump scene and it's kind of what I expected. It was a relaxing no brainer film.
