The Road had nothing to do with either(unless you count post-apocalyptic). The only scary parts about The Road was when they were in the house with the cannibals and hiding in the forest when the trees were falling. Great movie, but not all that scary. More sad than anything.
Yeah I don't do well with suspense or horror. The road didn't faze me. Had a few like "Oh No" parts to it but that was it. More sad than scary, I agree.
