Now here's a twist to the Christmas horror genre -- have the serial killer be killing Santa Clauses instead of the other way around. Sadly, that's just about the best thing Don't Open Till Christmas has going for it. This is routine slasher filmmaking 101 here -- with little regard for thrills or, for the most part, inventive kills. Actually, there's one scene for which the movie has garnered slight fame -- that being the castration scene, which is indeed a brave scene to shoot, even if it tends to come off more silly than stomach-turning. Edited with a herky-jerky style that makes the extra added gore scenes even more evident than they ever should be (the unfinished film sat on the shelf for years before being retooled for release), Don't Open Till Christmas is a laborious exercise to live through, no matter how unapologetic one's horror tastes are.
