top 5 is hard for me becuase i dont think you can rate something as big as anime in a top 5 list. Anime is a medium, not a genre. But anyway 1. Clannad(both shows together) 2. Anohana 3. YuYu Hakusho 4. Welcome to the NHK 5. Death Note
5 was a toss up and i really couldnt think of anything. I recently rewatch deathnote so its fresh in my mind and yeah it was amazing. Got its spot on the list. Honorable mentions but too cute/funny to make the cut K-on, Kill La Kill, Iwatobi Swim Club, The melancholy of Haruhi Suzuamiya, Baka to test, daily life of highschool boys, the list goes on.
I don't know if I can even name 5 besides DB that I've seen much of lol. So this will be more of an anime I've seen list rather than a top 5.
Pokemon(Currently watching through entire series. Only saw first season as a kid.) Digimon(Hey a ripoff of Pokemon) Monster Rancher(Another ripoff of Pokemon) Sailor Moon(I think I watched this before DBZ actually) Inuyasha(Only seen a few episodes)
Without including Dragon Ball and mangas (Vagabond would be in my top 5) my list would be: Death Note, Shingeki no Kyojin, Slam Dunk, Monster and Psycho pass (not ordered but would be probably like this). Akira could be there too but it's just a movie, need to rewatch it again because I watched it like 5 years ago or more.
