My kids were young in the days when video recorders were still a thing ( I feel about 100years old!). Anyway, there was a hell raiser marathon on once through the night, hell raiser 1/2/3 so I taped it. Came down the next morning to find they’d got up super early, my son had someone pressed play and my 2 and 3 year old were halfway through hell raiser 3 (having seen the full first 2 films). In fact my daughter loved pinhead and went on about him for ages afterwards!
Must be something about pinhead - I also "accidentally" watched it - when I was 3, I used to kiss the TV screen as I felt sorry for him!
