Anime....
As most ppl said here. FMA
IS a must. The story is addicting, It's really well balanced between comedy and drama. I recomend the movie too...tough I get the feelling the story is incomplete. There is a rumour of a 2nd movie on the way..maybe not.
Naruto: "How to ruin a story that seemed good" Fillers!!! run away from them!!!! The best thing to do is to start to see the anime..when u get the feelling u are seeing the same episodes over and over STOP. I learnt that lesson too late. I now have nightmares cause I saw 70 episodes...
Puni Puni Poemi: I don't know if anyone refered this OVA yet. It's just 2 episodes and it was made by the creators of Excel Saga...need to say more?
Note: If U haven't seen Excel Saga then your brain cells are burning.. *burns*
Hohoemi no Senshi - Grenadier: Recomended for guys with a Shermie/Mai fetish.
Tenjou Tenge: Good Good Good Good Good... *praises*
Gantz: If u praise the Anime but you don't read the Manga then you are an idiot.
Note: Manga is FAR better.
Golden Boy: This echi anime is over 10 years old but it's still one of the better ones to see. One of my favourites.
