It was good, the ending had me terrified to the point I skipped some scenes, worried that Billy would appear. Great for it's time and inspired Halloween. But there were many of horrible choices, for example why didn't Jess leave the sorority house after the cop told her to. Why didn't Barb just leave the attic after she saw Clare's corpse, and Billy holding a hook? Why didn't the detectives check the attic?
