The Evil Inside

Oh dear yet another film with a cast of actors playing stereotypical teens having a get together at someones house. We have the Jock, the close female slutty friends who via for male attention and ultimately fall out, the jealous boyfriend and his promiscuous girlfriend - enter the Jock, the rich party girl and the odd, creepy, ultimately psychotic one.

Sorry to say, same old, same old... get past what i call the dirty uncle plot (unpleasantly over familiar) plus the dire casting and the film is barely watchable, unfortunately it gets worse by the end of the film as the plot expands and you are treated to a blow by blow synopsis of what you have been unceremoniously treated to for the last hour and a half, instead of eluding to the initial story and letting the viewers fill in the gaps... it becomes very tedious.

Are there any original plots left in this genre?
