Nearly brilliant in all aspects I would say. The characters are well developed and all of them are like-able, even the villains too. Unlike most animes, the flow of the anime tend to fall off, technically being stagnant like Naruto and SAO. FMA Brotherhood on the other hand is able to keep viewers on screen all time, as the plot line is intriguing and filled with ambiguity in a good way.
The soundtrack of the series is arguably the best I have heard in a long time. The first opening and ending is legendary. All in all this a good anime if want to binge watch over the holidays. I personally think that this anime is a masterpiece and a classic and I do not frequently praise an anime so greatly.
