This would have been interesting if it had been shot in 3D. Usually 3D is used to give a sense of big, wide open spaces. I don't think I've seen it used to increase a sense of claustrophobia. And, since this film did manage to convey claustrophobia in spades, I would be curious to see how that would work with a 3D effect.
But, as a conversion, I can't say that I am too intrigued.
