Ah, the mountains of Manitoba. It is probably in poor taste to key on the threadbare and implausible parts of a low budget exploitation picture. Ideology is a fairer target, and/or convention. The romance, I mean, and the US butting in and enlisting our sympathy when the darkened locals object to their presence, and their compulsory ways. This is Manitoba, says the Canadian! (But it’s a British film…)
The implausibilities and the threadbare of the whole enterprise do kind of pall, until the threatened/promised fiends themselves eventually show up. Nasty! Cool too, and quite a technical feat.
