How long is this and is it worth watching? Just watched some AMV with it by chance.

it gets worse.
watch bleach instead

Eh it's alright. Plot is pretty linear, characters are undeveloped, and story is predictable. The theme of friendship also gets pretty old. It's well done though and I read the manga every week The action is alright but don't expect something impressive.
Instead of that I'd suggest watching Shingeki no Kyojin, Fullmetal Alchemist: Brotherhood, Sword Art Online, or something else.

Already watched those I'm looking for more hehe

not worth watching

this

Does it have to be action like that?
I'd recommend Code Geass and Darker than Black if that's the case (haven't seen myself just yet, but I'll get to them soon). Also heard good things about Hunter x Hunter (2011)

If it doesn't have to be that type of anime, I enjoyed Kuroko no Basket and loved Clannad

Seen those, and the other 2 is not of my liking ;p But feel free to recommend me some moar! :3

it's 175 episodes
IMO it's pretty enjoyable

Seems there are different opinions, I guess I'll give it a shot.
