I don't mind it, but I've never been a huge fan of the original. I think for a casual listener or someone who wasn't familiar with the original, this WS version isn't terrible. To a die-hard fan, I can see it being off-putting. I think that Beach's guitar work is as good or better than Blackmore's original and whoever the keyboardist is on this version is true enough to Jon Lord's original.
*shrug*
Guess I'm indifferent for the most part.
