What was / is the worst horror movie ever made?

What was / is the worst horror movie ever created, outright bad, rubbish, not worth watching.
Update: Ahh I see the popular sport of level 7's moving questions into different categories is still a thing here. Very original, very funny. Ha ha.
Update 2: I am sorry because you are all wrong. Seriosuly? The hills have eyes 2? It's actually quite a good flick. The answer is: Apartment 1303.
