I think that horror films have a very direct relationship to the time in which they're made. The films that really strike a film with the public are very often reflecting something that everyone, consciously or unconsciously feeling - atomic age, post 9-11, post Iraq war; it's hard to predict what people are going to be afraid of.
Eli RothI love movies that are just straight-up exploitation, but the ones that endure and the ones that last are the ones where the filmmakers put in that extra level of thought; after 25 years you put them on in front of an audience, and they'll respond to it and enjoy it.
Eli RothThe best movies now are called 'thrillers.' Because if you use the word 'horror,' people's associations are straight-to-video crap.
