Interesting that Rosemary's Baby and The Omen - the two biggest Satan spawn movies - both end with bleak endings. We really do have no hope against little Damian.

Perhaps the most depressingly bleak and hopeless for me is the ending to The Beyond. Haunted me for the longest time, I still can't think of much worse than their fates.

I'd say all of the above are very good examples of bleak endings - hopelessness is a very powerful feeling, and that lasting dread that it leaves undercuts the more primal fears of shock and repulsion by an awful lot.
