Yeah, I never had a problem with Jessie and thought he was a good addition to the show. It was some of the people he was aligned with in BB11 (Natalie, Chima, Ronnie) that were the problem.
Brian would have been interesting, though I suspect he would have been a quick target due to his reputation.
Cowboy was a unique character in BB5, but one I'm fine with not revisiting.
Jessica was, well...
