Do 당신 think the 애니메이션 is 더 많이 different than 이전 seasons?

I don't know why but the 애니메이션 looks different than 이전 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 애니메이션 in the show. So what do 당신 guys think.... Do 당신 still like the 애니메이션 또는 not?
