Due to the fact that it was filmed from reporter's cameraman perspective, I felt like I was dizzy (and I still am dizzy now) while watching this film. The plot is very simple but it could keep me watching it to the end. So, I'd say it's kind of watchable even if a lot of people would say it's not.
P.S. I kind of find that the main character, Angela is so annoying. I even wanted her to die and turn into zombie-like thing. (No offence.) Although it didn't show clearly how it ended, but I deeply hope and take it that Angela didn't survive. It's so sad that they didn't show the end of Angela.
