I think it's pretty easy to see why Lisa was a fan favorite while Dawn isn't. First; Lisa is a beautiful person and we all know that influences popularity at all ages and in all genders. Studies have shown that even men tend to hire handsome men with less qualifications over less attractive, more qualified men. Second and most important; Lisa came into the game with an entire segment of the population already in love with with Blair.
I'm on record here as disliking both of them for the same reason. They both played back-stabbing, ruthless games while telling themselves and everyone else that it was far harder for them than for their competitors -- the underlying message being because they're much nicer people.
Thank you Judy the Obscure.
This is exactly the reason I don't like either of them.
Also they both have a lot of the "helpless female" going for them. Lots of tears and lots of turning to others for help for emotional support. Neither of them repay any of that, and in terms of the game of survivor, that's fine. I just don't want to hear what good people they are or about there children etc.
