15 More Horror Movie Endings That Get Worse The More You Think About It

11. The Birds - They'll Probably Attack Again

Alfred Hitchcock's 1963 horror classic The Birds - in which birds suddenly begin attacking and killing people in California - is a largely magisterial film that perhaps fumbles the ending. It concludes out of nowhere with the remaining main characters driving away to a hospital and even though the house is surrounded by birds, none of them attack. It seems the phenomenon has stopped just as suddenly as it started. 

Well, that's all well and good, but what happens next? The first attack began out of nowhere, so what's to say another one won't begin just as suddenly? Furthermore, many people will have been killed or seriously wounded by the birds and those who survived will inevitably struggle to deal with their experience. Birds are absolutely everywhere, so those people will see grim reminders of what happened every single place they go. 

This is often the way with horror or survival films that revolve around large-scale catastrophes such as this. Viewers will be glad that the main characters made it, but that happy feeling will fade somewhat when considering all the other people who didn't.
