Some good "bad" horror movies

[Fearonsarms]

Ghoulies 1, 2 and 3 not seen part 4 though.

I never tire of "Spookies" 1986. Has to been seen...words fail me. "Dead Kids aka Strange Behaviour" 1981 is another...

Feast 1 to 3.
Gory, fun monster stuff.
And the monsters are people in suits. Usually better than CGI imo.

I wasn't really talking about simply entertaining...
I'm looking for something that's actually quite dark, scary, sick, etc.
Not fun.
Something that makes you stop for a second and go "whoa fuck!"

Sorry if I'm being to vague, but that's what I'm looking for.
But other suggestions are always welcome!
Thanks.

Some for the disturbing area are definitely HENRY:PORTRAIT OF A SERIAL KILLER (1989), THE REFFLECTING SKIN (1991-very David Lynch-ish) and although most people don't consider it a horror fil, DELIVERANCE (1972) scared me senseless the first time I saw it.
Other posters have listed some good titles as well like THE KILLER SHREWS (1959)and ROBOT MONSTER,(1953) and you can definitely throw in THE TINGLER (1959) as well. such audacious little efforts that are better than they sound
