I wonder how much is influenced by where we are and whom we're with.
For books, I recall my strongest reactions were at times that I was alone. I'm not sure if the effect would have been the same if every hour someone popped in and asked if I wanted a cup of cofee etc...
However, I guess if I really had to choose between the intensity of a good scare and marital bliss, I would choose the latter. At least we can both get scared watching a movie together.
