Discuss both Fullmetal Alchemist (2003) and Fullmetal Alchemist: Brotherhood here.
I just recently finished watching both series for the first time, and I really enjoyed them. While I personally think Brotherhood is the superior of the two series, the original seemed to have better pacing early on, with the possible exception of a few filler episodes. If I could somehow manage to take episodes from FMA and somehow fit them into the Brotherhood episode lineup, it would be really awesome, but alas, I lack the time and the patience. (Such a pain)
That said, I absolutely hated FMA's ending. I watched it first, and I really thought it was a horrible ending to the series as well as a terrible way of wrapping up character arcs. Then I watched The Conqueror of Shamballa, and it tacked on an ending that I somehow managed to hate more than the original one.
Compare this to Brotherhood, which I thought actually managed to wrap up everything quite nicely, concluding character arcs appropriately instead of leaving them hanging like the original did with some.
But that's just my opinion, what do you all have to say?
