I know its gotta b top 3, but for me it isn't enough.
1. Bakemonogatari series
2. Mirai Nikki
3. Stains;Gate
4. Death Note
5. Darker Than Black
6. Hellsing Ultimate
7. Attack on Titan
8. Code Geass
9. Gokukoku no Brynhildr
10. Btooom!
No Bleach/Naruto/Fairy Tail cos same crap in them over and over again, get ass kicked, miracle power, kick enemy ass. Repeat and you have these 3 animes. And ofc power of friendship bs.
One Peace is the worst anime I've ever seen.
Log Horizon>>>>SAO.
Also, not mentioning fan service animes that have 2819789 ecchi scenes.
