For me, as I stated above, I think, even though Dallas had been past it's prime for a while, I think season 12(13 dvd) would have been a good place to stop. They really tried to inject new life into the series that year, and even though most will say it didn't work, it was the last season that truly felt anything like dallas to me. You had the tanker collision, and Cliff having the chance to nail the Ewings once and for all, but he put his relationship with Bobby, and their ties to Pam into perspective, and went with what he truly thought was right in the end. Bobby finally expressed some emotion for Pam, and never getting to say goodbye; you still had Miss Ellie present, and caring about her family, and finally Bobby and April marry. The series ending with JR being stuck in the mental institution would have been a little funny and fitting, as opposed to a year later when he's contemplating suicide?? Once they knew Barbara wasn't returning, and Sheree only wanted to be in a handful of episodes, they should have stopped. Even though most of us of course wanted Bobby and Pam to be together, why not let Bobby find happiness if he couldn't be with Pam. To think the powers that be were ok with killing off April just in case Victoria "might" come back at the end seems crazy.
