Watching season 4
Some observations:
1. The Valene/Gary/Abby situation is just as frustrating as ever. Why was Val such a DOORMAT? Abby is really nasty to her: "I can have him any time I want him". And later, Gary is desperately trying to reconcile. If I had been her, I would have taken him back just long enough to laugh at Abby, and then dumped him, right in front of her. "You can have my sloppy seconds now, Abby. I'M his first choice. You're just a cheap, gold-digging tramp."
2. The Karen/Mack romance happens a little too quickly. The writers deserve credit for keeping Karen single for a whole season (contrast this with Pam Ewing, who jumped into bed with Mark Graison about 30 seconds after Bobby "died"). But I felt they could have had a little more buildup to their relationship. Instead, they are dating one episode after he is introduced.
3. The Richard/Karen friendship is very sweet, and something you don't often get to see on the soaps - a platonic friendship between a man and a woman.
4. Was Lisa Hartman really a big enough name to commandeer so much screen/singing time on the show? Every time she showed up, she's getting a 4-min scene to do a complete song.
5. Not sure why Kenny and Ginger weren't dropped a year earlier than they were. They have nothing to do, and are completely boring.
