ahh Dave, you must have seen the internet version. Don't feel bad, that's the only version I've seen also. But, the other night at work when we were watching it. A girl on my crew saw it in the theater and kept saying "that's different" with every 1-3am scene. Apparently the theater version ends way differently. The girl does kill the boyfriend downstairs, but then chucks his body back upstairs into the bedroom and then attacks the camera.... end of story. Apparently the producers saw the warm response in trials and rewrote the ending so there could be part 2, etc.. What was going around the internet was an ending that never made it to the reel (end up in bonus coverage on dvd).
Either way, don't pay to see it. I too thought it was boring. Maybe because I saw it at work, on a computer, with 3 other guys and a girl, and watching over a console to make sure things were operating good on the plant. It might be different in a theater??
