Personally, I was not invested in Gloria and John as a couple. At all. Although I preferred Joan van Ark's portrayal because it was more gritty, Gloria was a mess but she was shown as a survivor. I could've kind of seen how John might have admired and even been attracted to that quality, with Van Ark, you could see it. At least with Jill, you could realize what John might have seen in her but I couldn't see what John would've seen in Gloria, especially after the role was recast.
I'm not trying to knock Judith Chapman who seems like a down-to-earth genuinely nice person but the character had morphed into this over the top figure, that resembled a low-rent Jill Foster Abbott and I just wasn't interested.
I don't even know how the Baldwin/Fischer wing survived at all, considering how nefarious both Michael and Kevin were.
