For anyone who still cares, Fullmetal Alchemist: Brotherhood is now finally into the "new" material. Funimation is presently streaming up to episode 16, while Hulu is on a two-week delay.
Episode 13 was the introduction of Greed, and my own memory of the first series from that point is quite hazy. But the arc concludes rather differently in Brotherhood, as I definitely do not recall Führer King Bradley busting out the twin blades last time. Then, with episode 15, the story fully diverges from the 2003 series.
Kind of an odd feeling watching this show. I was surprised at how pleased I was to see Ed and company back for more adventures. On the other hand, this second take more or less renders the entire latter half of the first series meaningless, which can be difficult to come to terms with, since there was some good stuff in those episodes.
