An animation company simply should not be taking CLAMP's characters and trying to develop them how they feel is right when the characters don't belong to them. BeeTrain, like the rest of us, don't have the full picture of what the characters in Tsubasa are all about, which is the reason their filler episodes make so many glaring mistakes.
It's CLAMP that created these characters, CLAMP that know these characters inside out, know their reasons for acting certain ways - what drives and motivates them, and only CLAMP that have the right to change the way they think, feel and act.
I hope that has something to do with copyright or any legal stuff, that way CLAMP could emand BeeTrain and change studio
