A good job.
I enjoyed this movie a lot. It wasn't LOL funny, but it gets across a good chuckle from me. I especially liked the grim reapers reasons to be happy to die. I wasn't aware of the interchangeable parts thing. :-)
Although the art was pretty good, I thought the animation left a little bit to be desired. Most of the characters looked very (VERY) similar. Granted, that is the style of the artist, but I still wanted some more variety. Maybe an anchorwoman or female interviewer out in the field?
Overall, a job well done.
