"Without them, there would be no slasher movie. Seriously. They gave us the first-person perspective during a murder, the successive beautiful women getting stabbed to death, the gratuitous sex, even the idea of revealing the killer's identity during a final confrontation with the last survivor. Really, what's Friday The 13th if not an American giallo?
And sure, you might be able to name off the big ones: Deep Red, Blood And Black Lace, even Seven Blood-Stained Orchids. But this list isn't about that. It's about the weird gialli, the ones from big names and nobodies, the ones which slipped through the cracks. There are ones in here which amount to incomprehensible gibberish, and ones which are so beautifully plotted it'll make your head spin. Ones with tons of death and ones with very little, if any. I like to think there's something here for everybody."
