I made the mistake of watching this (curiosity got the better of me) even though I KNOW I am constitutionally incapable of dealing with horror movies.
After I watched 28 Days Later I couldn't sit with my back to a window at night for a week. After I watched the Grudge I couldn't go into elevators for a month.
Since watching this trailer I have developed a nervousness when opening my closet. So here, have some heart palpitations and a few new basement phobias, whydontcha.
