This is "style over substance" done to the extreme. While visually stunning, even hauntingly beautiful at times, there's utterly no point to any of it. Add to that the ridiculous and sometimes painful dialogue and extremely slow pacing, and you got quite a mess in my book. Now, that is not to say it does not have any redeeming qualities - the visual aspect is one, so is the soundtrack. And, well, Nick Cage is .. well, Nick Cage. (YOU RIPPED MY SHIRT?!)
I have to assume it is an inspired watch if --and only if-- you're watching it while higher than high. That must also have been the state of those who made it, let alone greenlit and financed it, because despite having so very little to offer in terms of storytelling, it must have cost an arm and a leg to film and produce.
Anyway. Unless you are extremely into artsy, pretentious, drawn-out gore-fests, give this a wide berth.
