There was actually a lot of promise to the premise of an ageing Scream Queen taking revenge on her younger replacements, and at times this film touches upon that and really could have been something special. However overall it is hard to recommend a film that just shows promise but never truly delivers.
In this case the premise is let down by the lack of plot and acting, something the film itself references (points for trying but simply saying 'our film doesn't really have much of a plot, just tits and violence' isn't enough to excuse this, especially when as film- makers you are self-aware enough to make this point). Also as a side point, as a movie that rests its hat on exploitation, in terms of nudity; there is some, but not anywhere near as much as you would perhaps expect. The violence too is lacking somewhat due to budget and imagination.
Furthermore the movie premise is hamstrung by a lack of viable victims to begin with, as such the movie attempts to stretch out deaths and has nothing to fill in the time with. Perhaps if the characters had been better developed then this would have been more effective, but there really is nothing added past their bios given in the first few seconds of their appearance in the movie. If you are going to use these women as just bodies to watch and chop then why not have seven or eight with some fun deaths?
So overall the movie can only be described as a let down, lacking the appropriate level of talent, fun and even nudity to really justify more than a casual watch if you are a fan of boobs.
