As sleazy horrorsploitation ideas go, you can hardly imagine any better than "Inmates escape sanitorium. where they are undergoing 'LSD therapy,' and thus think they're dreaming everything when they attack a girls' choir and their minders whose bus breaks down in the English countryside."
The thing that is most impressive about "Killer's Moon," however, is that it's so ineptly made there is almost no lurid camp value--and, needless to say, no suspense or terror. The acting is highly variable, from competent under the circumstances to laughably bad. But no one is helped by the terrible, plodding dialogue--which, incredibly, author Fay Weldon (who contributed to the script because her brother was the director) later bragged about, feeling in retrospect it was a mistake to gift her excellent writing to such an otherwise poor film. Well, she certainly sank to the occasion, even if obviously her ego survived the experience. It's the crap dialogue that provides the rare unintentional laugh here.
The violence here is for the most part laughably mild (in fact mostly off-screen), the behaviors psychologically ridiculous, the continuity gaps mile-wide, and the pacing deadly. I really hoped for some guilty pleasure with this one, but it is just a slog.
