By the time we reach the infamous dinner party sequence in The Texas Chainsaw Massacre, we’re terrorised already. And then this happens. It’s savage, it’s horrible, it’s OTT and it’s bloody, bloody brilliant. Final girl Sally (the best Scream Queen ever, Marilyn Burns – rest in peace) is subjected to the Come Dine With Me from hell as she gets to know Leatherface (Gunnar Hansen) and his family a little better. This includes a comatose and pretty dead looking Grandpa (John Dugan) sucking her cut finger, then in a horrific moment of black humour failing to bludgeon her. You want to stop watching…but you can’t. It’s beyond scary.
