The three that immediately sprang to my attention were:
Grace, Army of Darkness and Dead Girl. Grace, I have seen and reviewed, equally loved. It was well worth watching and a movie I will be buying as soon as it comes out 
Dead Girl (like many others on HM) I have harboured an interest in, so this is on my 'must see' list and well do I need to say anything in regards to Army of Darkness?
True I have the DVD, but I have the barebones version with just the film and one trailer so a chance to own the DVD with some added meat is a chance I cannot pass by! I think I will def. be willing to fork out money for these 3 films.
I do agree though this is a good month for horror, the list is awesome!
