I'm a 24 years old swede who mainly likes odd sci-fi shows (preferrably devoid of mechas) like Texhnolyze and Ghost In The Shell but is also very fond of things on the opposite side of the spectrum like Digi Charat and Ghibli movies. I guess you could say that what I like the most is things that doesn't try to be much more than entertaining.
Most if not all animes that tries to be deep and thoughtprovoking fail at it because they fail to realise that anime is a visual media. In visual media you work with moving pictures as you all know so sticking long monologues that could as well been part of a book is poor storytelling. While I have nothing against shows bringing up philosophical concepts it always goes to far when a character suddenly has to explain how it all works. No doubt a hard thing to balance but when it's done right it is glorious, sadly it very rarely is.
So, when I review shows that simply are often gets bonus points while most that tries to be deep and thoughtprovoking gets a point deduction simply because they fail at it. My ideal animes is in other words Laputa, Castle in the Sky and Cowboy Bebop while the absolute worst anime I know of is Elfen Lied.
Anyway, my scores works as such;
1 - There is nothing nice to say about things as vile as the ones I award a 1. The only show I've ever seen that I dislike this much is Elfen Lied.
2 - Very very bad, there are few things worthwhile about these shows if anything at all.
3 - Still awful but the show might have some minor positive thing about it. Bad generic ecchi like DearS might fit here.
4 - Subpar and boring, the bad things still outweigh the good ones even though there might be some good points.
5 - Mediocre and lackluster but might interest fans of the genre.
6 - Shows promise and is interesting enough to warrant a full watch. Though still some bad things about it.
7 - Definitely a good anime, while there may be issues it's still recommended if you like the genre.
8 - Without a doubt a highly watchable show, the good points far outweigh the bad ones though there still are minor problems.
9 - Great shows that I recommend anyone to watch, very few faults with it.
10 - Only rewarded to my personal favourites, while perhaps not perfect in my mind they are damn near.
Also be reminded that everything I write is opinion, if you disagree with me feel free to argue but if I don't like your favourite anime just don't take it personal.
Finally the overall score will often vary wildly from the rest of the scores. My overall score is what I thought about the show, whether I actually liked it or not while I'll try and be at least somewhat objective when setting the other scores.
