I don't understand the line: 'Even the gameplay, relevant in 1983, was dated.'
Are you saying the gameplay of the original was bad? (Obviously it can't simultaneously be relevant and dated). Or of the NES version? What's the date of the NES version vs the original? This line is too vague for me on an important point.
I haven't played the NES version (and I'm a NES skeptic. Not a superskeptic, but I have seen enough ports of games where the NES version is what everyone knows, and it's the bad one) but I don't understand this comment. I'm moved to comment because, even though I had infinitely fewer critical faculties when I was 8, I was there when this game was new, and it definitely felt new. The stuff I remember thinking was coolest was - how the guys went in and out of the doors (so it was like an extra dimension) and how your karate kick move accounted for the scenery. That is, you could try the kick at any point in the scenery, and depending on where you were, you would move differently. This is really just a long way of saying 'You had a modicum of logical interaction with the scenery', but most games didn't have that. A jump was a jump. You couldn't jump and bump into complicated stuff like ceilings and elevator floors etc., and see your guy react accordingly, like you could in Elevator Action.
Does the NES give you the ability to shoot the lights out, also? Also as qxz said, it was the first game I played where you and the bad guys could actually walk through each other and nobody got hurt.
