The scores I give are meant to reflect what the anime meant to me personally rather than an objective assessment. As a general guideline of what my scores mean to me
10-9 - Favourites: I'd recommend them to anyone
8 - Really liked: Very good shows that could be close to greatness.
7 - Liked: I'd recommend them to certain people if that's what they're looking for. But I wouldn't exactly call them great.
6-5 - Meh: Either because it has nothing that's either good or bad or has plenty of good things, but plenty of bad things that cancels out the good.
4-1 - Bad: So bad that technically it has negative value (6-5 are my starting standards)
A more specific score is given in the Tags column as over time whole numbers became too restrictive. Specific scores aren't given for anime in the 4-1 range, specials and some stand alone OVAs. There will probably be some exceptions to these rules that have their own specific reasons.
