I'm no fan of Jackson. I even think he's an average director who got lucky with LOTR.
But really, what the books were trying to tell has to stop being used as an argument by discontented fans.
Being faithful to the source material or its themes is not, has never been, and by all means should never be the point of adapting a novel to the screen.
The LOTR trilogy is a great cinematographic saga that stands on its own, as it should.

As for answering the OP's question, I'd be glad to see the remake of basically anything, classics or not. There's no such thing as an untouchable film.
If the remakes are better than the originals, then fair play to them, I'm always pleased to see a good film. I won't forget the originals, I'll just like both and enjoy their differences (i.e. Millennium - TGWTDT)
If they mess it up, well, who cares? Having a sh**ty remake does not make the original any less good.
So bring on remakes of the Star Wars OT, PT, Blade Runner, LOTR, Batman, Jaws, Terminator (why just the third one? Let's remake them all), whatever... I don't care, and I'll wait in line to see them.
