See, Carl, I'd almost agree with you, except for two things:
1) I felt it was wrong how Annie had to go psycho in order for the triangle with her, Josh and Reva to be interesting.
2) B&E especially took Annie, who'd had an average and "normal" background, and retroactively wrote her as someone who'd been off the proverbial beam all along.
Co sign on #1!
I remember at the time the triangle was going on that Kim Zimmer remarked that she didnt understand why they had Annie go crazy when the triangle had been an even 50/50 split beforehand. If I were a soap writer, I would kill to have a triangle that evenly split and would write the hell out of it!
Even if the show wanted Reva/Josh, I would have made Annie eventually realize she was too good for Josh and move on. That would have been more interesting then turning Annie into a one note psycho.
I actually liked Annie in the early months of the show, she seemed like a tortured soul trying to make a new start in a new town. Plus, she was a nurse.. carrying on a long tradition of featuring a long suffering nurse (Peggy, Katie, and Lillian were featured long suffering nurses... I figured Annie would be next in line to carry the torch.. given early scenes between Lillian/Annie when she first joined the show).
