That's because a lot of them on Twitter are Liason stans. Liz with psycho Ric again does nothing for me because I could never believe she'd be with him again after the 2000s and the panic room, though I enjoy Ric for what he is (a crazy slimeball).
I had no particular fondness for LNL2 in the '90s, I found them too saccharine, but the older version appeals to me. JJ and Becky still have it if not moreso now that they're older IMO. It's just that Jonathan's return interferes with the show a lot of the Twitter kids had planned in their heads, so they act very vocal to project bigger numbers than they have. (Similar case in point: The supposedly massive fanbases of Sonny and Nina, Michael and Willow, etc.)
