Actually, if you've never seen the original film, don't ... at least not yet. It would be interesting to get the point of view -- especially from a serious film buff such as yourself -- whether or not this film actually works on its own merits. What an amazing control group you could be.

Finding out if this movie works with NO frame of reference would be awesome.

Then, maybe in a few weeks, you could watch the official version and compare that way. They're going for cheap on that megastore of a website that's named after a river in South America.
