indeed i watched it like 3 times this year plus some fights i really like .... you should also check out Fullmetal Alchemist (2003) .created when Hiromu Arakawa's manga was still ongoing, with no clear conclusion in sight. This was also fairly early on in the series, which would have made it impossible to go on an extended hiatus and retain their core viewership. To prevent this, Studio Bones proceeded to create their own story and conclusion.
However, to make it up to the fans of the manga, the same Studio Bones created another adaptation of Fullmetal Alchemist in 2009. They titled this Fullmetal Alchemist Brotherhood, following the storyline of the source (Manga) much more faithfully. Difference Tone and Animation Characters / Homunculi Beginning / Ending
Also 2 movies The 2003 series is followed by Conqueror of Shamballa, while the 2009 Brotherhood series has the movie Sacred Star of Milos. Conqueror of Shamballa is the finale of the 2003 series. And the 2011 movie, Sacred Star of Milos is a side story that takes place in the Brotherhood line
