I watched FullMetal Alchemist Brotherhood that follows the manga faithfully. This movie is not following the manga faithfully, obviously. Anyway, I think it is not bad overall. The storyline is decent and it paces too fast. I didn't pay attention to acting, but I don't see any issue with their acting. Rewatch Value? Will rewatch it if it have the second movie because it left the story opening.

If you prefer to have movie that must follow the anime or manga faithfully, then I don't recommend this movie for you.
