1. Samurai Cop
27. Chopping Mall
these 3 would probably be in my top 10. Good list
I'll add Hospital Massacre, Aerobicide, Ultimate Ninja, The Wraith, Eaten Alive (Umberto Lenzi's, not Tobe Hooper's), Ghoulies 2, and The Mutilator
Edit, didn't see you put the entire Ghoulies series in there as well. They're all bad, but I have to say Ghoulies 2 is the only one I thought was bad in a 'good' way.
