GRArkada uploaded a video not too long ago, explaining his own rating system. I thought this was a good way to rate anime, dividing it into sections consisting of story, characters, animation and sound, and adding his own personal enjoyment score. However, I don't regard myself as a "professional" reviewer, and I only seek to share my own opinions and discuss others'. Which is why, when I review anime, I don't make individual scores for all these points.
In my reviews, I like to talk about what I think worked well and what didn't. Of course I consider the different sections, but they rarely play a big part in my final score, unless they really stand out (like the voice acting in Suzumiya Haruhi and the animation in Hyouka, for example). When I give scores, they're mostly based on my personal enjoyment of the works, which is why I have no problem giving 10/10 if the work got to me. According to Arkada himself, the perfect 10 does not exist, and although I somewhat agree to that, some animes/mangas/etc are good enough for me to rate the highest. That simply means that they're one my favourites, something I enjoyed so much, and in my eyes is a masterpiece.
|Prettiest anime in the world.|
10 - Masterpiece
9 - Great/amazing
8 - Very good
7 - Good
6 - Fine/not bad
5 - Average, "meh"
4 - Bad
3 - Very bad
2 - Terrible (or as Arkada would say "kill it with fire")
1 - "The fire is not working, nuke this bitch" (Thank you very much for that fine description, Arkada)
Anything with the score 8-10, I'm highly likely to re-watch, up to several times. Works with a score 7, I might, anything below I'd rather not. Although I actually have no problem watching things I thought were bad over, just so I can point out what I didn't like and hate on them some more, as long as they didn't completely bore me.
To sum it up, my reviews are quite biased, I'll admit. But again this is my blog and my opinions. Still, I love to hear what other people think, even if our opinions differ, and welcome you all to share your feelings in the comments.
