Why has the disney movie themes been poor performers?

Disneys themes seem to perform terribly. Not just one but all of Them. Cars and toy story being the worst of them all But even the potc sets have done poorly with the exception of the ships. Why do you think these sets have done so poorly on the after market and do you think the Lone Ranger, Star Wars and the super hero theme could follow (with the exception of exclusives)
