New material is useless if the material is bad. Live-action adaptations of anime have long since been terrible. Movies like "Dragonball Evolution" (one word? Really?) and the Netflix "Death Note" movie have been slammed by critics and fans alike.
Creative reinterpretations can often have disastrous results. Whether it's whitewashed casting, costumes that just don't work in real life, or over-exaggerated acting and effects, there are a lot of aspects of anime that just don't translate well into live-action. Animation as an artistic medium allows for fantastical stories to be told and imaginative things to be shown which can't be reproduced in live-action filmmaking. Putting something that is fantasy into a more realistic medium takes away the magic and charm which made fans appreciate the anime in the first place. It's best to let animation stay in the realm of animation.
