Though not a twin myself, I have a similar opinion on the "creepy twins" thing as Blatherskite (and I agree with her concern over the conjoinedness being a cheap thrill).
That being said, I kind of want to see this a little bit anyway. I love horror and I have very strong nostalgia for Nickelodeon. Throw in a little morbid curiosity and an appreciation for both Frank Langella and Jim Gaffigan.
I don't have cable, and the date has passed anyway; does anyone know if this is viewable online?
