I never felt like the original was too out of tune with the source material.
It will be hard, I think, for them to keep the serious tone though. Everything nowawadys is so smug and nudge-nudge-wink-wink see how hip we are. It'll end up being, well, like Arnolds later movies, where it's all about the one liners, or they'll go over the top with wire-work action sequences. More Scorpion King than Conan (not that Scorpion King didn't have some enterntainment value).
Plus, they'll make it PG-13, so no real blood n guts, and no topless Sandahl Bergman wannabe, either.
