Too smart for it's own good
First of all, "The Corridor" is a fantastic movie. It intertwines a Lovecraftian horror, a fear of an unfathomable alien entity and an analysis of the psyche of a common man, which actually scares the fore-mentioned even more.
Let's face it, the typical horror-viewing public is a bunch of numbskulls and teenagers who just want to be entertained with some blood-spurting, well-known monster cliches and an occasional boob flash. Take that away from them and they're lost. "THIS ISN'T THAT ONE THING I KNOW! IT'S SOMETHING DIFFERENT AND I HATE IT!" is a common reaction, and ironically it demonstrates xenophobia pretty well. The part about 5 childhood friends who have grown up into fully grown individuals and realized not only that they have little in common, but that most of them are losers and *beep* makes people uneasy even more.
The whole film makes the common man uneasy and an inquisitive man excited, and I loved it for that.
It deserves a 7 because of it's obviously very limited budget but I gave it an encouraging 8.
