review for Bloody Birthday on AllMovie

Bloody Birthday (1981)
by Jeremy Wheeler review

Kid killers roam loose in Bloody Birthday, a "slasher in jammies" that makes The Omen, The Bad Seed, and virtually any of other evil-kid movie seem like a puppy dog in comparison. A product of the early-'80s line of low-budget slashers, it's not surprising that this horror gem sat on the shelf for three years until 1986. Who in their right mind would have the guts to release a flick with kitchen-knife wielding brats that also blow people away with huge handguns? It wouldn't be as good without this cast either, with extra gonzo points going to each kid as they take maniacal glee in plowing down everyone in their way (including their parents). A spit in the face to the family values crowd, Bloody Birthday is a bloody-fun time that's great for all of the wrong reasons.
