I have only one word for scriptwriter and director: :baka:
If you're a real fan of Akematsu-sensei's works the you should not watch this.
How can anyone mess up such a good manga is beyond me. After great Ala Alba and Mou Hitotsu no Sekai I was anticipating another faithful adaptation. I couldn't been wronged more.
Not only creators decided to miss the most interesting part of original story (giving barely a little preview at the OP) but they also had guts to exchange the ending with some half-witted story.
Not only story itself is incoherent, and the plot illogical, but also psychological profiles of characters are altered (some to extreme extend).
The most annoying part (story wise) is the change in pactio system and personality of Evangeline. Why are contracts expiring just because girls are graduating from middle-school? And why the hell the evil master mage Evangeline is happily becoming pactio partner of her student? Looks like creators didn't really read the manga to make such blunders. Or were they aiming to make just an C-class "Power Rangers" Show for 6 years old, since theres definitely many flashy effects in part that should not have any?
The only thing that stops me from sending a furious-fan bomb mail to whoever decided to make this poo is hope that maybe in the future some real team will decide to make a full remake just like it was done to FMA. Don't have any more strength to waste writing about all the smaller and bigger lesions done to this great title. If your dead on to watch this then be ready for a path of thorns.
