THIS IS OUTDATED... MY VIEWS ON ANIME HAVE CHANGED A LOT SINCE POSTING THIS... PLEASE CONSIDER NOT READING THE BELOW TEXT.... I WILL UPDATE MY PROFILE ASAP...
The ratings below are completely biased. Don't give way to peer pressure and hype cause enjoying anime depends entirely on your tastes and expectation (why you watch anime, what you want to see, what you want to feel, etc). That doesn't mean mainstream shows are bad, only that it depends on you as an individual if you enjoy it or not. With that out of the way, this is how i rate. [last edited: 04/10/2017]
::::::::My rating system simplified::::::::::
Broadly divided into four categories as follows:
The Best Animes:
#These shows are unique for its characterisation, plot, sounds, etc. Value themes, inner voices, thought provoking elements, all sewed together with praise worthy story telling and direction. Has the 'wow' factor that screams perfection in a way. Has higher viewer satisfaction. Totally recommended for re watch.
10/10 - Masterpiece
9/10 - Outstanding
The Good Animes:
#These shows are very enjoyable and worth a thumbs up in their respective genres. There are inner meanings, thought provoking elements, praise worthy setting and direction as seen in the former category. Minor flaws in story, story execution, slow or fast pacing plot, abrupt ending, characterisation, etc any one or more together affects the overall enjoyment. Again, these anime are good for re-watching.
8/10 - Great
7/10 - Very Good
6/10 - Good
The Ok Animes:
#A lot of shows can be labelled under this category due to coalescence of several factors.These shows generally have potential but have major factors gone wrong or not suiting in a way. These shows might also have mediocre plot, but other factors covers up the obvious downsides. These might also be shows which focus on execution and enjoyment rather than the content delivered (moe themed). Broken plot, poor character development, poor characterisation, poor sound, poor vocals, lack of animation (based on year of release of courses and genre), unacceptable or vague themes, slow or fast pacing plot, abrupt ending, overused the plot devices, etc are also some of the elements behind these ratings. In a nutshell, these are acceptable for the entertainment it packs though not leaving a mark. Mostly not re-watched in general; it depends though.
5/10 - Fine
4/10 - Acceptable
3/10 - Poor
The Poor Animes:
#These shows have poor setting and plot to begin with. They may deliver some enjoyment and zest but ultimately fails to deliver the basics. An eyesore. Sometimes ruins your expectation so badly that you go all nuts. Totally NOT worth watching. Need i say re-watch?
2/10 - Bad
1/10 - Hell
Note: Some of my ratings doesn't follow any of the above criteria.
