The only good thing of this movie is its final twist. In 97 minutes of film we can only save one single idea, which was totally wasted in this movie I must say! For more than 90 minutes this film is just a collection of clichés, bad acting, stupid ideas and disclosures, complete lack of suspense, stupid deaths, terrible special effects; all this in a pathetic and unoriginal plot until the last three minutes, where, FINALLY, a good idea appeared! It's nothing outstanding or an extremely original idea, but, at least was a "decent" good idea, the only one the entire movie has! I won't spoil it, but I must say I think that idea with a better plot, better FX and, definitely, a better acting, would turn into a good film. If you watch this movie and can stand it until the end you will know what it is
