This is a nice, if not particularly original, idea, of a 'cursed' film, which, if you watch it - YOU WILL DIE!
Unfortunately it doesn't quite come off. The modern-day framing sequences really talk up the cursed nature of the infamous film, and then we - gasp! - get to see it, with a stark warning beforehand that you do so at your own risk.
However, having watched it, I didn't die, so I don't think the film was cursed at all, really. However, had I died, I would not have been able to write this review.
The film within a film, 'Antrum', supposedly filmed in the 70s, is nicely done and the retro feel is perfect, but the problem is... it's not scary. Not even a little bit. And it's totally confusing what's going on. And the stuffed squirrel and 'cannibals' are just hilarious.
I wanted to be enveloped in a miasma of dread like you get watching, for example, Von Trier's Antichrist, which I almost stopped watching half-way through, such was the all-enveloping atmosphere of evil of that particular film. But this just enveloped me in a miasma of... nonplussed boredom.
As executors of the late Alison Low, who did not heed the warnings and passed away towards the end of watching this film, we have been asked to review the DVD rental as follows:
There is a good film in there about siblings digging their way into hell. It's a bit like Alphaville, only with demons. The viewer has to use their own imagination to appreciate the five levels of hell contained in the film. The guff and hype round the movie was not required. The 3D effects were irrelevant and only proved to be an annoying distraction to the viewing. I ........ (it was at this point Ms Low passed away).
