I personally *really* enjoyed NnT. It is a ridiculously good remake of such a classic game.
However, after completing it I played the first half of AO again to compare.
I agree with a fair bit of what Slog Bait said, though personally my main gripe doesn't come from the exaggerated and goofy characters, but rather the change in tone in certain environments.
It sounds silly but I thought that RuptureFarms (whilst still looking awesome) was too bright and colourful and futuristic. It has lost some of the dark and fearsome aspects of the factory's original appearance. All the levers and trapdoors have bright flashing lights all over them, the walls and floors seem to glisten with shiny cleanliness and there is just an overall lack of grit.
Really, the intro serves as the best example of this. Gamespot has a few comparison shots up and one of them shows the bit in the intro with the Mudokons pulling the levers to move the meat across the belt. I thought it looked amazing in NnT, but when comparing it back to the dark and, to be honest, terrifyingly grim look it had in AO I kind of realised that this was my main issue: the oppressive and distressing tone from AO has, in some respects, been dampened. For example the bright colourfulness within RF. When coupled with the exaggerated characters I sort of understand where Slog Bait is coming from in terms of his tone argument.
ANYWAY. That was a bit pointless but just my two cents and all that :P aside from that the game is truly wicked. It blew my mind with how good it was not only as a remake of a classic, but as a modern game in its own right.
Therefore, well done to JAW and OWI
Oz out.
