10 - I'm overwhelmed. I don't think I would watched another title as good as this.
9 - Great. Probably one of my favorites. I'll never get tired watching this again and again.
8 - Good and rewatchable. I'll probably rewatch this once or twice.
7 - Good but I might get bored rewatching it. I'll probably rewatch the good episodes only.
6 - Decent but meh. Boring stuff but I'll still watch this. No rewatchability value.
5 - Not Good. Dropped midway but there is a chance of being resumed (On-hold). If not I must be really bored with it.
4 - Bad. Dropped at episode 3 or shorter. I'll never watch/resume this again.
3 - Terrible. I feel terrible watching even an episode of this.
2 - Beyond Terrible. Disaster. A waste of time and money.
1 - Beyond Abysmally Horrible. An anime that shouldn't exist.
