There were a lot of terrible choices made that year (and the cuts Valente made were terrible in some cases, like getting rid of Andy, although if they had not done such an awful job of bringing in new characters/actors it wouldn't have mattered as much), and the history and continuity and family feel were ripped away, never truly to return, but sometimes it does feel now like the old Joni Mitchell song (later repurposed by Janet Jackson). I remember Soap Opera Weekly complaining about Nancy being in a storyline about being potentially swindled by dance teachers, and how the closing credits had her wearing a clown nose....not great, but a world away from her just being there to cheerlead Katie. I also remember Michael Logan being aghast that ATWT reportedly had no long-term story plans at that point. I question if they ever did again...
To me much of her 1997 run is unwatchable, and even the "better" material afterward does not feel like ATWT to me and also just has a very seamy edge (Emily's endless obsession with Tom, to the point of using information said in confidence at a rape support group...or so much with David/Reid). The choices she made with Carly also genuinely befuddle me. I hated most of what ATWT did with Carly in the '00s but at least in cynical terms I "get" it. I don't get choices like her marrying John Dixon and him inseminating her without her knowledge.
Denise lasted about 3-4 years, although they never knew how to use Cassandra Creech. I always liked Denise, but I'm not sure she ever fully recovered from her intro, which not only was unsuitable to the remaining ATWT conservative audience (selling her baby), but also included commentary on race that I don't know if ATWT, or any soap, was capable of addressing (her calling Camille "high yellow").
