Considering that re-runs of the Cosby Show and Roseanne are already back on the air, I wouldn't count on a permanent ban on her old stuff just yet. And even though I'm pretty disgusted by the charges against her, there's no reason to punish the fans and workers of WCTH by pulling the show mid-season. Slightly off topic, but this is the reason I wish recasting was more common in TV (just like on the old daytime soaps). There have been too many shows over the years derailed by behind-the-scenes disputes and scandals, and in many cases I'd much prefer an actor switch, than a show cancellation.
I'm pretty sad about the end of Garage Sale Mysteries. It was one of my favorite series, and I fully support a new franchise starring Sarah Strange. There are plenty of cozy mystery series out there, no need to re-tool GSM with a new lead. And I know I'm in the minority here, but I really like the actor who plays LL's husband, and would love to see him in more Hallmark movies. His character is a total drip, but I like the actor. As far as filling the hole in the schedule, I would like a few more Emma Fielding movies. I know they're not the most popular, but I love history-based mysteries, and would love to see more of them.
I doubt it would ever happen, but I would love for them to make some cross-over mysteries. A mystery surrounding a collection of old books would have been the perfect Aurora Teagarden/Garage Sale cross-over, but since that's not happening, they could have Jill Wagner's literature professor character be a guest speaker at Aurora's Real Murders club, and then the two solve a mystery together. So many possibilities!
