I was done when Pam disappeared. I hung on for a few episodes of the 87-88 season, because I thought they’d recast Pam and wanted to see if they could pull it off. When they had her disappear (and the family didn’t give a fig), it was a big letdown. I tuned in briefly again at the beginning of the following season to see Pam’s cameo/resolution. And that was it for me.
