In my mind, the animation was better than in the first seasons. I have to admit, that some scenes were unfortunately not able to keep up with the rest (third OVA: Fay looked like a fish desperately longing for air O.o). Nonetheless the storyline was very interesting and not so easy to understand, which I find very exciting.
All in all "Tsubasa Chronicles - Tokyo Revelation" is something, fans should watch while keeping the manga in mind, in which the emotion and drama is portrayed much more intensively. =)
