Ken Coffelt’s review published on Letterboxd:
Slaughter High takes place in an alternative universe. In England, “public school” means the exact opposite of what it means in America. Maybe that’s why this not quite gothic mansion of a school stands in for an American high school circa the 1980’s.
But really, logic and reality are shirked at every turn, so much so, you stop really caring, even when really outlandish things happen (outlandish by even genre standards).
The kills in the movie range from benign to bizarre, and the latter ones are also done with quite cool practical FX.
I too was brought to mind of Terror Train (1980) in which the promise of sex turned to cruel prank leads to psychosis and slaughter. Only in Slaughter High, that prank is just the start. It only gets worse and for a slasher, there is quite a lot of story behind what turns poor Marty (Simon Scudamore RIP) into a vengeful, scarred jester. The ending takes a turn quite unusual for the genre, adding further character to the whole shebang.
It’s weird. And I kinda liked it.
