Watch Eyeball in tribute to the late great Umberto Lenzi. Ocular violence is probably my biggest fear so this gets to me despite how funny the whole movie is. It's very disturbing to me.
Lenzi did like 7 or 8 Gialli and Spasmo is his most triumphantly mental. Just go with it and forget about a cohesive narrative for the duration. I'm sure you'll enjoy it. There's actually a better version on youtube Posted by Giallo Realm which won't embed here. So maybe search for that one. Happy Halloween.
