Oh no, I completely agree.
I just didn't want to imply that it would be an automatic flub.
You are right; animation would allow for a much more...attainable...effect. One example could be the Animatrix, or, for the CG Endeavors, Appleseed Ex Machina or other attempts like Spirits Within or Advent Children.
For a WipEout movie of that caliber, though, it seems like it would cost a very large sum of money...
