I beg to differ. This is not about low cost production. Through my understanding, this is a high budget film although the directional of the film kinda different from the manga. Being a fan of its comic and animation, I do agree that the film is far from its original. But you must understand the realism they want to relate with real world. Seriously, it is not tolerable to see a dude with such hair in real life or blue hairs. If you think they didn't put the blue wig or turtle shell due to low cost, you're totally wrong there. Despite what they presented is not up to our expectation (especially the anime lovers), bear in mind that what they are currently doing will cater audiences from other levels. Not necessarily anime fans.
