The ending to this arc is one that couldn't live up to overall expectations, especially the way the final arc has raised things to such a high level. When you look at the individual parts, there's a whole lot to like. The final moments against Father are spot on, the emotions of those supporting the Elric brothers is inspiring and the connection shown between Greed and Ling is really beautiful. The big part of the show that really comes to fruition here is the most understated of pieces, but that's part of what makes it so wonderful. The sacrifices made by the brothers, the whole Brotherhood angle of the name in the US in fact, is shown in such a simple manner with no regrets that you can't help but to love both of these young men all the more. And their story is spot on here, making it the culmination of a wonderful journey for them that has a future that is wide open.
