The TNG bridge hasn’t aged well at all, IMO. The static displays look just as stagey as TOS, and there’s a tremendous amount of dead, wasted space. Add all the beige and it looks, well, dull, which I would never say about the TOS bridge.
I think it fits the "technology unchained" idea Roddenberry was running with early in TNG. Though that idea got ditched in the follow-up shows and movies. I understand the reason why (the sets look more interesting with lit up panels everywhere), but in TNG it seemed like they were really striving for the future in the initial conception and designs, much like TOS.
