I remember being super disappointed with AYITL first came out, too. But I think it has something to do with age. Back then, seeing Rory spiral and struggle to find herself at the age she was seemed illogical to me. I kept thinking "that's not the Rory I remember."

But I'm the type who rewatches GG every six months or so, and the last time I saw it, it hit differently. Maybe because I am now closer to Rory's in-universe AYITL age? Ha! But I have definitely warmed up to it as a revival. I just wish we'd seen more of some of the other characters. Four episodes was too short!
