I just started watching S06 (1987-1988) of Cheers, and this is the first time I've ever seen these Rebecca Howe episodes. Great casting & writing. Kirstie Alley is the total opposite of Shelley Long's Diane in many cases, but her sarcastic comments/commentary are great, and IMHO she may even be a more interesting character than Diane. She definitely has a harder, more businesslike edge to her, but at the same time is extremely attractive - even without necessarily meaning to be Also wanted to mention that this 6th season has a completely different feel/vibe than what was seen in the previous five seasons. I.e., the bar has been sold to RH's company & has gone "corporate", so is much less "homey" than the previous five seasons. In one of the first S06 episodes, Sam comes back to the bar after having sold it & trying to sail around the world (presumably it's only been several months) - and barely recognizes any of the customers. Yes, RH "replacing" Diane Chambers seems to be the only real major cast change. However, I wonder if the bar being sold was not only a way to "change things up" on the show, but was also a kind of social commentary on how local, small businesses were being bought up by large corporations - something that seemed to be happening more often by the late '80's.
