If It had picked up where it left off, they could have killed Vince off (killed at work?) and had Grace divorce Leo (again) for cheating (again) and their married kids could be living away from New York - I think it would have been cool to see their lives break down and need each other again, putting them back where they all started - alone but together.
In all honesty ignoring the original ending just gives them a chance to bring back Beverley Leslie, as we don’t need Stan, and Jack being rich wasn’t a bad thing - he could have easily lost it all funding a ‘Just Jack’ Broadway run, and Karen could be married to another unseen billionaire (or perhaps even Trump’s mistress).
As much as I love that the show is back it’s sort of a bit sad knowing neither Will or Grace got their happy ending with a family and kids they both craved for years during the original run. I’d have liked the parallel with their kids popping in (as guest stars) criticising their parents’ lives in much the same way Will’s parents and Grace’s mother used to.
