The only problem I have with remakes is this:
They're usually failures in relation to the source material from which they draw inspiration, and they usually fail in their own right. They lack any real substance, whether borrowed, stolen, bastardized, or original. War of the Worlds, IMHO, was just a Tom Cruise movie with aliens. It bore little resemblence to the original source material--making it a bad remake--and fell in line with the recent trends of cheap suspense, overdone special effects, and shallow storyline. Substance? Who wants that when we can have STYLE?
That's where deference to the source material comes into play. Why did the Dawn of the Dead remake succeed? Because, like the original, it wasn't so much about a zombie apocalypse as it was about human society falling apart on every social level when faced with extreme stress and danger. John Carpenter's Halloween was a study in evil and a masterpiece. The character of Michael Myers was frightening because, in that opening sequence, we see a sociopath (in the form of a child) at work. Unlike the hillbillied version that Rob Zombie brought to us, this classic Michael is a young, seemingly affluent boy with no real reason to kill anyone, let alone his (we can assume) beloved sister. John Carpenter makes the audience face the possibility that this boy is just bad. He was born bad, he will die bad. That's the real horror of Halloween, and Rob Zombie missed it. See, good remakes (and movies, really--or, perhaps I should say "films") aren't about the flash and glitz, but rather about heart and soul.
As for the original version of The Day the Earth Stood Still, I'm quite shocked and more than a bit appalled that one wouldn't recognize how "vintage 50's special effects" would have ruined a little thing in the movie called "atmosphere"--the very thing that has made it a sci-fi legend, and the one thing that will likely be lacking from the remake. Truly, you missed the point and, likewise, the best part of the original. But, that's the majority of this generation of movie-goers, isn't it?
To paraphrase KMFDM (and to close my rant), pop-culture is the only kind of culture we're ever going to have.
