1. Baccano
-Short story (16 episodes) and it's hard to follow since it uses the same technique as pulp fiction (placing everything trough each other). But it was one of the best shows I've ever seen, the characters were amazing and everyone was so interesting and likeable, even the enemy.
2. Afro samurai
-It might have ONLY 5 episodes, but those will be the 5 best episodes of your life. The contents might be for 16+ sometimes but it's really deep and a nice serie. The fact that he made an illusion of his own irritating companion, till the fact that that illusionary same companion saves his life by throwing himself in front of the enemy's sword, while it is actually his sword blocking it.
3. Full metal alchemist
-Longer than Baccano, I think about 80 episodes and it ends with a movie. It was a very good serie and for some reason it had logic behind it, even though it was fiction. It has a good storyline and I enjoyed every episode.
4. Bleach
-Even longer then full metal alchemist but at least it already ended. In the beginning it was hard for me to follow, but at the end it was worth it, though there are a couple of things that didn't seem right in the series. For example, SPOILER ALERT: Spoiler
Ichigo could easily beat Aizen in the end, but why using his last getsuga Tenso then?
5. Naruto
-Great concept, great idea, great storylines and the decisions the writer makes from living or dying is excellent. Spoiler Alert - Jiraiya:Spoiler
I even cried a bit with the dead of Jiraiya, perfectly made and my favorite character. But I wasn't angry when he died, I was happy since he died a dead fitting for the toad ninja
For the rest, the fillers and flashbacks are killing me. Also because of all the fillers and flashbacks it reached so many episodes. Use only the story and he would have about 200 episodes, a few from Naruto, and a few from Naruto shippuuden.
6. One piece
-Humor is more the basic of this series while epicness also had it's way there. It also has a few fillers tough, but less as naruto, also less flashbacks. I wasn't sure who to put on 4, one piece or naruto, but since I'm more fan of naruto I chose that.
7. Fairy tail
-Not so good, has it moments but no one die's in the series, not even people who were dead before the series started, since the little sister came back from another dimension. Also it's to childish, to much "For Friendship" attitude. I don't know why the series stopped in the middle of the tournament, that was also a sad moment.
