10/10's = Near perfect where next to nothing is wrong unless sifted through with the finest of combs to where any complaints would be just be nitpicks. Also leaves an impact so great that it practically impacts how I view anime going forward.
9/10's = Fantastic series that might have some minor issues in execution. Still among favorites and will always fondly remember for moments of greatness with only slightly less impact than the big boys.
8/10's = Still Great but might have some glaring issues outshined by the good. About where anime that I would highly recommend begins. Anything here or higher for me is considered a gem.
7/10's = The absolute lowest you can go and still be considered good for me. An overall positive experience that just leaves a good feeling rather than an actual lasting impact.
6/10's = The absolute bare minimum of the good outweighing the bad. Clearly flawed but still redeemable. Basically these are average shows with just enough to take something overall positive from it.
5/10's = Middle of the road, mediocre, and or mixed bags all serve as suitable descriptors for these. I literally feel nothing towards these as they are usually painfully average but still defendable.
4/10's = Bad but usually not insultingly so. The beginning of the end if you will. The point where the negative elements start winning out in that everlasting battle of how I feel about something.
3/10's = About where pointless and or trainwreck worth material start appearing. Where almost nothing is executed well. Wastes of time begin here.
2/10's = Absolutely horrible. Plagued by flaws. The sooner these can get out of my sight and mind the better. Usually only have glimmers of hope or ironic enjoyment to keep them from the bottom of the barrel.
1/10's = Nothing redeemable at all. Literally nothing that makes feel "Wow, I totally did not just waste my life watching this." Only fun to talk about if only to rip on it for being a failure in every regard.
I don't rate anything I haven't finished unless it was dropped for being bad and or uninteresting so a hiatus is fine.
I don't rate every sequel season or part of a series unless its separate enough to where it needs to be like Naruto Shipudden but will just leave an overall score on season 1 like on Code Geass.
Other things that may affect rating :
Filler problems = -1 point because it is skippable
If a series is left unfinished at an unreasonable endpoint = -1 point (some unfinished series are fine where left off.)
Also, every series that share a score on my list I find to be of pretty even. So like Monster and JoJos I enjoy just as much as each other but for different reasons.
