5 stars - the top among the top, a flawless piece of anime I find extremely enjoyable, which influenced me in some way and that I couldn't stop thinking about for some time.
4.5 stars - a wonderful piece of anime I enjoyed very much, but which lacked the special "something" that would make it absolutely perfect.
4 stars - an amusing anime, that is definitely worth watching.
3.5 stars - an anime I consider slightly above average - it has its weak points but still interested me to the point that I was able to finish watching it without extreme boredom.
3 stars - an average anime, which doesn't offer anything special, but that wasn't a complete waste of time.
less than 3 stars - an anime I find disappointing and consider a waste of time.
NO RATING - IN CASE OF INSEPARABLE ANIMES I RATE ONLY 1 SEASON/EPISODE. THAT MEANS THE RATING IS COMMON FOR ALL SEASONS, EPISODES, SPECIALS AND MOVIES. Additionally, I usually don't rate OVA's or Bonuses. In rare cases I don't know how to rate, so I just leave the rating empty.
