I grade based on feeling and enjoyment. Meaning these are obviously subjective. I tend to find so-called "objective" views of things to be boring because I think one's enjoyment of something is based on a lot more than such strict things as the "rules of storytelling." It's how I can still enjoy some things even if they are ripe with many flaws.
I also only went down to "5" because I don't know what to say about anything lower than that. Once again it's based on my feeling and shows with scores lower than 5 are shows that I have no particular feeling about except that I felt they sucked on different levels.
5: These are shows I felt were just plain lame. They don't have much redeeming value and I found very little to enjoy in them. There may have been one or two enjoyable bits in them, but overall I'll just forget about them pretty quickly.
6: I found these shows to be decent...barely. They're a bit below-average and I probably thought the concept had potential but couldn't fully realize it. I didn't feel like I completely wasted my time watching these and might even watch a few of them again years down the road just to see if my opinion had changed (and sometimes it does).
7: These are shows I felt were good but nothing really special. Mostly average, maybe sometimes a bit above. I liked them but don't dwell on them and don't think about them very often.
8: These are the shows that have potential to be a favorite of mine. Not a "top" favorite, but a favorite nonetheless. These shows are often unique, or have very solid writing with great or interesting characters. They're not always the best but I thoroughly enjoyed them and would watch them again without a problem.
9: These shows are great! Many of my 9's find themselves into my list of top favorites. Gripping, interesting or fun storytelling, great characterization, often times the music and animation are top notch which add to the experience. An all-around excellent package that I can really sink my teeth into. These shows are always good to remind me why I became an anime fan.
10: I don't throw around 10's easily. 10's are special to me. Special in many ways. I consider them masterpieces for different reasons. No, they are not perfect. Nothing is perfect. But as I've said before, it's all about feeling. These shows give me a special feeling. I've found myself deeply connected to the characters and the story and just about every other aspect of the show that you can imagine. Some of these may flawed, but I've found myself so gripped that I easily brush them off, or I may even come to like some of said flaws. But that's the power of a 10. It switches me over into a whole new level of enjoyment.
