I have no problem with animation, I just don't think that an animated series would suit Animorphs. And I have plenty of imagination thank you.
Why go through all the touble of setting up a false identity for Ax just so that he could go to school with them? It's a dangerous security risk as he could accidentally let something slip, not to mention that he would quickly become bored with a human education system which is greatly inferior to his own.
And yeerlover, you actually like the idea of turning Animorphs battles into a cartoon style fights with no blood? Why not just add in POW, ZAP, BAM and other effects on screen everytime they hit anything?
