10-Masterpiece. As close to perfect as it could get. Most likely my personal favorite or a milestone in the anime/manga industry.
9-Great. Very few minor flaws that affect the overall experience. Exciting all the way through.
8-Really good. Could gladly recommend despite a few drawbacks. High quality, interesting story and characters that you care about.
7-Decent. Worth watching even though it might lack consistency. Has some faults although they don’t distort the story that much.
6-Above average. Liked it but noticed the shortcomings here and there that don’t serve the plot at all. Has a few pleasant aspects to offer which outweigh the faults.
5-OK. Pretty much the middle point in the scale. Things I like and dislike are balanced. Might have been just boring.
4-Poor. Has glaring flaws that affect the entire, rather miserable, image of the title. Uninteresting but the concept itself might have been good, unfortunately executed badly.
3 and below-Pile of trash. Score depends on how many minor enjoyable things I have noticed. Not worth watching whatsoever. Something to pick on or joke about. Probably will cause to make you think what you are even doing with your life. Total waste of time.
