I want to go back and rediscover TNG all over again and I really wish I could! But that's just a fantasy that reminds me how joyful the series is and what it's always meant to me. It's a thing of beauty!
ENTERPRISE: These Are the Voyages... kind of demonstrated the inappropriateness of a TNG return, though, even by that point -- and we're talking, like ... a decade ago! Yes, I have always maintained that I enjoy TATV and I am not backtracking on that. I LOVE Riker and Troi ... and the fanwankery carried me over that Suspension of Disbelief, amongst other things, to get me to dig the show. However ...
I have ALWAYS amended that with the admission that Frakes and Sirtis had visibly aged out of their parts. I really felt bad for Marina, as she'd already gotten beefy. Frakes looked haggard, despite colouring his hair and beard. All of this made worse by the fact that their characters were meant to be as they were, years before. It didn't flatter either actor. By the same token, Jonathan and Marina had been guest starring in other STAR TREK series, all along, so it wasn't that unforgivable seeing them do so, again. But it was clear that the time for that kind of stuff was over. It was time to move on and reinvent themselves, some way. It's the only way to get their sparkle back ... living in the past doesn't do the trick.
