Hmmm, one of the most impressing things in the legend of the seeker, is those slow motion effects. Don't know if anyone can make it (yeah i know that cheat, but i mean that you go from normal to slow motion and reversed).
Next to that, it is very difficult to create a person who looks like the ones you did see in the series (you do need very much polygons to create a face resembling the face you did saw).
