This has got to be my favorite version of the Cinderella Story so far. Now, Cinderella as a character in general is my favorite character, so I'm a little biased. But in every other Cinderella movie, I have never really felt like I've watched Cinderella really progress at all. In general, Cinderella stories are short - Abused girl has to do all the chores, is nice and kind to everybody, isn't allowed to go to the ball, gets magicked into the ball, meets the prince, Glass slipper - it can be summarized very easily. But this show does a very good job of ... not really dragging it out, just adding more to the characters. More story. I still get to watch and see who Cinderella is and how she reacts in a whole slew of situations without just seeing the abused girl suddenly get to go to a ball.
Now... I think there is one complaint I have about the series. I'll be honest... Cinderella, in this, isn't really the brightest, and the Dialogue is lackluster. Some parts are repetitive and redundant, and there are a lot of flashbacks that I think are a bit needless. Suspension of disbelief is sometimes ... eh. And the animation isn't always the smoothest. You see some obvious cycles in there at points.
But by and large, this is still my favorite version of the story, and there's a lot more character development in this than there is in any other Cinderella, which makes the characters more realistic and more likable... even in the step-sisters sometimes. And there's more plot involved, with some political intrigue here and there. I love it.
