5 stars = god-tier ... Anime that has captured my heart. I consider these shows to be the best ones I have ever watched. Each one of these is very special to me and I will certainly never forget about any.
4 stars = above average ... You won't make a mistake by picking any of these.
3 stars = average ... Entertaining, yet easily forgotten. There certainly are better shows to watch. If you feel like watching something undemanding, you can feel free to pick any of these.
2 stars = below average ... I don't recommend watching these. For me, they were just a pointless waste of time. There are many wonderful shows to watch, so it is kind of a waste to spend time on garbage.
