At the end of the day, it's not about whether or not you find it scary, but whether or not you find it fun.
I can remember a year or two in which I wasn't really scared, but was entertained and had a blast. Though, often times I found the 'scariest' houses to be the original ones rather than any IP. Still, I agree with Rikku, the older I get, the more I go to just appreciate the set design and costumes. It's the best looking event by far in the US, I think!
