There are a couple of movies that come to mind that are worth watching, even though they are older and might not be as well known and lack the shock/gore factor. IMO, they are definitely worth looking at.

The two that come to mind are "Carnival of Souls" and "Don't Look Now"

How about suggestions for some more, possibly obscure, horror films that are worth seeing to get a good scare....You know, possibly a movie you've seen, thought was good, but can't find too many other people who have seen it.

Why is it that some things scare us more than others?  I guess it depends on our personal experience and imagination. 

For me, the things that scare me are the things I can't see, but imagine might be there, you know, the things that go bump in the night.  Which for me is not necessarily a good thing....

You see, being a flight attendant for the past 22 years, I spend a lot of time alone in strange hotel rooms.  Of course, the urban legends we were told when we started flying didn't help.  Seems there was a flight attendant who didn't show up downstairs to be picked up with the rest of the crew.  The captain called her room and she said she was having trouble finding her one shoe.  The captain went up and helped her look.  He started opening the drawers (which we never use on overnight trips) and in one of the drawers, there was her shoe....along with a note that said "thanks for letting me watch you sleep".  Yikes! that one still gives me goosebumps.
