OMK! This was the hardest pick ever! No,no,I'll say both.

The animation in MT2 was pale and smooth. The animation in PCS was ugly, to be honest. The characters look way too ugly and most of the time, you can barely see their eye color. Just look closely and think about it.

I'm not sure .But for me the characters looked better in PCS than in MT2 .I think the same as Adri .They both have a realistic animation,and I like that .

I REALLY REALLY LOVE IT SO MUCH.

MT2's is realistic as same as PCS's
but It's not too bright like other modern movie

but I pick MT2 ^^

Well, both movies have similar animation, but MT2 looks more smooth just like MelodyLaurel said.
I think PCS looks a little awkward when the characters were walking or moving

I personally think both had good animation, however, I think that MT2 was better as the movements felt more smooth and natural, and the characters looked good (without beign too much)

Blair is prettier than Merliah, but MT2's animation is better than PCS'. I think Mattel has improved their animation quality.

I thought the characters were really pretty.

PCS Better

Much better color and shading.

The colors weren't too bright.That's what you mean.

I feel as though Princess Charm School does, but the animation for Mermaid Tail 2 is pretty good.
