I have nothing better to do atm, so I watched all 7 episodes. And I honestly say I liked it. Sure, the filming wasnt Hollywood stunning, but I expected that from an amateur film. The story line was slightly weak, and on a few occasions, made a bit confusing by the "flash backs". The thing is, these people put their heart and soul into the film. I kept half expecting the dead bodies to rise up as zombies... but hey, thats just me.
I can totally understand why the students would stay on campus. Its "home" or comfortable to them, a safe place. I know that if I had no clue what was going on across the city/world, and had no contact from other people. I wouldnt wander far from home either. None of you would.
The show did get better towards the end, as the smaller storylines came together. I have to say, I much prefer films like this, than the continuous flood of sequels and re-makes coming out of the seemingly uncreative Hollywood Machine.
