Quoted from Rarehero:
Every DMD game has "cartoonish" characters on the DMD, except for when Stern started to rip movie footage, which usually looks awful...it won't be changed - this is the direction that's been decided on. Even with overwhelming complaints about Beast's voice in X-Men & fake Optimus Prime in Transformers - they never got changed.
Generally I would agree with you here but I'd rather have a bad looking rip than the two stick figures continually running. I bet they will be adding detail and more dots so I hope they can make them much better than they are now
