]I think it looks promising. I love the Korean Film, and am a big Chan-Wook Park fan, but this looks to be dark, gritty, and violent like the Korean film. Yeah, there are some changes, but I don't think it's any different from the ammount of changes the Korean film made to the original Japanese manga. Whether this is terrible, decent, or as good as the Korean film, well, I just have to wait and see. From what the trailer sowed, it looks interesting. I haven't seen any of Spike Lee's other movies, so it's kinda nice to go into it with an open mind.
As for the whole "This movie shouldn't be touched" thing, what's the damage, exactly? The original's still there. Nobody's telling you you can't watch the Korean film ever again. This is simply an alternative, just another interpretation of the same story. I mean, even the worst remakes never ruin an original film or franchise. Look at Dragonball Evolution. Yeah, it sucked, but it didn't set fire to the entire franchise (Dragonball sort of did that to itself way before Evolution.) When people bring up Dragonball, we know what they're referring to.
And whether a remake is pointless or unoriginal, it doesn't stop something from being entertaining.
