I watched loads of horror films as a kid which kinda desensitised me to gore and thrillers. But Tales from the Crypt: Demon Knight was intense. I watched that when I was 12 after my Dad fast forwarded through it to check it wasn’t too horrible. He must have been out of the room a lot, as there was a sex scene and a heart torn out of someone’s chest.
The evil guy is Billy Zane which is a massive bonus. You can find clips on YouTube of him punching through a guy’s head and ripping it clean off.
It’s fantastic. Also I had a weird childhood.
