The interesting thing about this, is how the animation technology seems to be their gift and their curse.

It got good enough for them to make timely episodes and definitely enhanced the series, but after watching the documentary that Frank Drebin was talking about, it seems that it's gotten so good that they can literally throw something together in six days and that appears to have hurt the show's quality in these later seasons.
