The film was made in 9 days and it shows. In particular, the budget obviously wasn't large enough to cover a decent recording system. Through out the film in scenes of dialog (and for a horror film there are a LOT of scenes of dialog), the character in screen is recorded loud and clear and the off screen, second voice is inaudible.
Music video-style fast cuts and scene shifts that move backwards and forwards in time are not so much confusing as meant to try and downplay the lack of much plot or its illogic.
The cast is generally quite good and makes a good attempt to overcome the inadequacies of the script and production.
