Do Ты think the Анимация is еще different than Назад seasons?

I don't know why but the Анимация looks different than Назад seasons. Like in the episode "The Knights" Penny looked completely different than how she looks in other seasons. The shows still good, it's just that i don't know why they changed the Анимация in the show. So what do Ты guys think.... Do Ты still like the Анимация или not?
