To all a Good Night has long since been touted as one of the worst of the genre pieces from the benchmark year in slasher shenanigans. But to be honest, it's really not that bad. Mark Shostrum's gore effects are great, and Jennifer Runyon makes a cute and approachable surviving girl. This is, of course, the first SLASHER movie to include a killer santa, which would be repeated in Santa Claws, Silent Night Deadly Night, Christmas Season Massacre etc. etc. Just for the sake of originality (!), Don't Open Till Christmas opted for a masked killer that killed people in Santa suits instead!
The only problems with To all a Good Night is that it's poorly lighted, a little off the wall and perhaps too under-produced. But it's certainly not the worst of its kind and is just about worth hunting out.
