Personally 28 days later scared the hell out of me,
Not so much the movie itself but the premise behind it, at least body snatchers/night of the living dead they moved like mollasses uphill in January but in 28 days later they run at full speed,
Creeeepy.
Yeah, that and the sequel. I can't wait for the next one in Paris. It's going to be sweet to see the French get it.
