I originally saw this as a web-series. It was a series of actual youtube blogs posted by this University girl, Genesis, with a new post every day or two as her haunting played out over the course of a couple months.
Now, all this found-footage has been edited down into a movie, and it'll keep you watching to see what happens next.
As other reviewers have said, what really keeps you watching this low budget, web cam film, is the lead actress's performances. It's so totally authentically a blog, there are times you're not sure if it's scripted or real or what. She is literally 95% of the film, and her acting is delivered right on the mark, staring face-to-face into the webcam.
It's a low budget (or even no - budget maybe?) but it's got that found-footage authentic feel, and worth the watch.
