High Tension (Haute Tension) was marketed a while ago in the UK as Switchblade Romance (for some strange reason), strange that it was given an anglicised name yet thankfully (for what it's worth) it wasn't dubbed at all, unlike sections of the US release.

I'd have to agree with arsaib4's review and found the plot fairly obvious, the death of the father was like something out of Monty Python and was ludicrously funny (in a bizarre way). It would obviously help your enjoyment of the film if you're a fan of the slasher genre, fortunately I'm not but it did have fairly decent production values unlike some I've seen. 

What's the point of High Tension ,Haute Tension, Switchblade Romance when these films are a dime a dozen, do we need a French slasher flick? the only answer you'll get from me is non.

Cheers Trev.
