any recommendations that are actually good?

it's hard to suggest, because most of them you probably have seen already.
But check out the descent if you havn't and The exorcist (1973) or the evil dead (1981)

some other stuff:
the thing
the shinning
night of the living dead (1968)
a tale of two sisters
28 days later
