I liked it.
It was announced as a horror movie, but that doesn't cover it at all, it's more a thriller, maybe you can even call it sci-fi, since the story deals with hopping through time and dimensions. On the other hand, that may make it sound too pretentious, it's actually a very small project, no special effects, just a few major characters, hardly any settings beyond a few houses and some streets, clearly a low-budget thing. But within these restrictions they did a very nice job, I found the story entertaining and original and the acting surprisingly good. I especially liked Travis Tope, he has this endearing Tobey Maguire quality and he is actually very funny. Don't mind the panning and sour reviews, just give it a chance, you'll be surprised.
