Paranormal Activity. It was alright, but not really original by any means. I think one of the main problems with it was that stuff only happened when you were expecting stuff to happen.
Also, apparently this movie was made with $15,000. I cannot fathom how they spent this much money. I mean, I understand that they payed the actors like $500, but there were like 4 people in the movie. And it was shot on your basic digital camcorder. Add in a couple microphones and I guess we might be up to like $5,000. Where did the other $10,000 go? They shot it in the director's house. Did he have catering? Why would you do that for like a max of 3 people at your house at the same time? I'm pretty sure they just edited it themselves too, so I don't know maybe the cost of FinalCut or Adobe Premiere is included.
