I don't think Badderly was Schnessel.
I really think there is a big difference in quality from Schnessel's run to mid-90/early 91 (Rauch's end). I mostly base it on the writing for Gabrielle, but even beyond that, like the tedious Charlotte story, Johnny Dee/Tina, et al. From what I've seen of that time the only story which really gathers my interest is Viki's stroke.
I actually think Faux Bo is kind of a fun little story, at least from the clips I've seen. The only part I find distasteful is Tina/"Bo", and then Tina being pregnant with his baby and going out the lighthouse window. 1888 I also enjoy, just for cheese and for some great acting from Clint Ritchie and Erika Slezak. It may have run too long but was a nice set piece.
I think even with O'Shea, the show still had its flaws - look at the waste of Dorian, and the issues with the Sanders family. Ultimately Rauch was such a dominating producer that his way ruled, even if it hurt the show. I think Schnessel managed to work well within Rauch's scope. I do agree O'Shea was better though, and her pacing was pitch-perfect.
As for Michael's murder - Brenda was supposed to be the killer. At the last minute they chose Roger instead, which is why he wasn't even on the SOD cover. I don't think anyone cared for the rewrite, but then I'm not sure anyone liked the story in the first place.
