strangely...i have never noticed it as a season 1 and 2 since I watched all 51 episodes in one go.
Really don't know how to vote for this though, it is true that Leon and May were incredibly mean to Sora during the 2nd half but without her suffering, i don't see how the finale can be made that beautiful....and I think that ending performance was definitely more superior compared to the Sora-Layla performance at the end of the 1st half
I voted for the first season because I liked the Sora/Layla interactions. As mentioned before that went away some in the second season even though it did have some of those moments that made up for it. I found the first season's ending more impacting. If the second season ended with Legend of the Phoenix then it might have been a different vote for me.
I love the first season where she gets to do all kind of things to make her a better performer. But I think the second one is better because she makes it to be the True Kaleido Star. And the last episode made me cry.... ^^'
I think season 1 because it's where every thing started. That's where everyone started being friends and it was a fun place. But with the second it seemed more... I don't know but it seemed to me much different.
