"I accept the premise, therefore I enjoy Anime."
My ratings are based solely on the enjoyment I got from watching the show/movie. I can enjoy a 'meaningful' anime as well a whacky, pointless series. While I certainly notice an excellent level of animation (or a particularly bad one), the quality of an animation and/or the score or soundtrack hardly influence my ratings. A crappy story is a crappy story, even if the animation is excellent. This holds true the other way around.
Another factor is that I bought many of the anime I have watched. For this reason, I seem to have too many good ratings than one would expect on average. It is just that every bad show means equals a waste of money, which makes me try to choose carefully which anime I am going to watch next.
The default rating is three stars.
Proceed at your own risk.
