The reason for the Tsubasa anime’s ultimate failure is because someone thought it would be a good idea to throw the manga plot out of the window and make it up as he or she went along. And this is displayed in all its hideous and unfortunate glory in the (thankfully) last outing of the anime series (and one can easily guess why). Totally removed of aim and faithfulness to CLAMP’s original work, the last few eps scream out a “let’s call it a day” call of desperation. It is so bad it is almost cringeworthy to watch and one wonders who let such bad error of judgement slip pass the producer’s shredder unquestioned. Indeed, it could have been a lot worse. At least you get the box to house the DVDs (to protect it from the dust of the attic).
But one should not despair, for the OVA which was created after this stuck to the manga and saved the anime form, albeit in a different format and production company entirely. There is a God after all.
