I am a 30 something female. I took my partner to see this, well i wanted to see it and dragged him along and we saw it in 3d. Whats it about? Its about kids getting eaten by Pirahna fish. Thats it. Thats the plot. So if you go and see this expecting Miss Marple you will be disappointed. Is it good? Not really. Is it entertaining? Oh yes. Is it gruesome? Of course and thrown in for good measure is lots of nudity, full nudity from our very own 'i want to be taken seriously as an actress' - Kelly Brook. How anyone could take this film seriously i would never know as its done very tongue in cheek and is meant to be that way. Is the acting good? Yeah for the type of genre of this film i would say the acting was really good. Jerry Oconnell was fab, just fab, I loved Christopher Lloyd, his over acting makes him who is and the Richard Dreyfuss touch was good also. The only one to let us down with the acting I would say is our very own Kelly Brook again. But she is there for eye candy isn't she? Anyone going to watch a film about teens and Pirahna fish not expecting girls to be sunbathing topless or expecting graphically gruesome deaths must not have a clue about this type of film at all. It basically does what it says on the tin but with decent actors - for a change. I would recommend this film for 18 - 30 somethings, especially the boys, although don't get too excited unfortunately most of the girls have surgically enhanced assets that look even more fake than the CGI fish! Sorry.
