If you feel strongly for a film, vote for it. Please don't abuse this though. I really don't want to see Cabaret on the list.
I really didn't want Taxi Driver on the list, because I love Taxi Driver. Knowing that some people didn't vote for it because they don't see it as horror would leave it somewhere near the middle or bottom of the pack. It would just look tacky having Taxi Driver wedged between a couple of merely good horror films.
