Originality: zero points. But hey, if you read the synopsis and behold the film poster of "Killer Book Club", and you are still secretly hoping to see an original and unpredictable slasher mystery, then I am sorry to announce there's something very wrong with your expectation management. "Killer Book Club" - or "El Club de los Lectores Criminales" as it sounds much cooler in Spanish - delivers exactly what it promises: pretty & posh, but empty-headed teenagers getting brutally slashed by a freak in a rudimentary clown's mask. Too insulting for your IQ? Please watch "Poor Things" or "The Substance" instead.
This sick Netflix puppy takes its inspiration from the two biggest (not necessarily the best) horror blockbusters of the 1990s, namely "Scream" and "I Know What You Did Last Summer". A group of (fake) campus friends plan to scare the bejesus out of a pervy teacher who went #MeToo on a student, but their prank naturally results in a gruesome death. Immediately after the mandatory "I swear I'll never tell anyone!" sequence, the group finds themselves pursued and relentlessly killed by someone with a mask and a mountaineers' ice axe. Will you hope & pray for someone in the club to survive this horrible ordeal? Not particularly...
Your first guess for the killer's identity will probably already the right one. Every "twist" in the script is laughably predictable and even the finale is blatantly copied from the aforementioned 90s flicks. Don't think. Don't get annoyed. Simply enjoy the gore.
