why we think it should be an animation.

we've got the script, very cinematic script. therefore why should we make an animation based on it? it's an important question
in the very moment, the only answer would be 'to get my degree'. doing something only because we can do it is a non-sense, and in now, something we would like to create, probably would come out better as live action. maybe we should do it this way then?
the question is what are the pro's of showing this as an animation. at least partly animated live action. what could it be. the cult of Captain Tsubasa? a possibility of exaggerating action in the scenes where Pacha plays football to make it much more interesting? or the need of 'distancing' the seriousness of the script? why the hell do we want this to be an animation?
in my opinion, quite the contrary - to abolish Tsubasa's myth.
to put an end to thinking, that cartoon has to be light and sweet, and when it's adult cartoon: it has to be iconoclastic and loaded with swearwords (though we'll smuggle in some f-words, but not in the way as it is in South Park or Wlatcy Moch). I think it's worth to make it as an animation because there is a sort of 'gap in the market' for this kind. this gap is being slowly filled with animations like Renaissance, Persepolis or, recently Waltz for Bashir. and it sells well.
Of course, a handful of common reasons: because we can manipulate the picture in every possible way, play with the mood and colours, what, with our equipment and our technical possibilities is impossible as a live-action-only.
Last but not least - cartoonish background of the film does emphasises its paranoism. we just have to go away from anime-like Tsubasa and come out with something new, not-renaissancesque, not-southparkesque, not-animatrixesque.
