Relentless until it stumbles

Rating: 5/10 (16 August 2014)

The best review for this was by Admarple on p.48.
I'll just add that this movie is relentless horror until a complete switch of tone at about 75 mins - the mood music goes all violins and we end up with a different hero. I suspect the producers overruled the director. So the Three Labours of Hercules (MacGyver style) that had been set earlier in the movie went to the sister instead of the brother. Basically turned into a chick flick, with a Caravaggio chainsaw slaughter at the end.
Not sure it was worth remaking, even with a more grim/less camp approach - nothing really original added, although the addiction rehab was a good idea that didn't have time to develop. And the blond was mysteriously pointless - did she die? I forget.
I was thinking 7/10 halfway through, but it ended up as a 5.
