A great sub-story addition to the world of FMA: B. I enjoyed the increased quality of art and animation that was present in this movie. Definitely worth a watch if you have seen FMA: B. I think the story got a little bland, however since it basically just copied the same idea from FMA:B another bad guy, more people dying to create philosopher's stones. I love the characters from FMA:B so this movie won me over still. I would recommend that you watch this movie after you finish watching FMA: B if you have not already. I did enjoy that the writers for this moviedecided to explore an area of the world that had not been previously explored in the series.
