Bones animated this series and they did an excellent job, I really liked how Envy's "true form" (the huge green body of dinosaur, head of dog thing with the bodies of the people that were used to create the philosophers stone) was drawn, and I also liked how the Elric brothers were drawn. You will either love a character or hate them... or have a love/hate relationship with them *cough cough Kimblee*
This anime will have you laughing until you cry and also have you crying your eyes out if you get touched by stories. There are some really funny moments thrown in there and some feel breakers. The story is incredible and at times it has you wondering if some villains are all that bad...
FMAB also has a great cast list in sub and dub like

You will become completely hooked on this anime and it's kind of impossible to hate it. But I highly recommend it because it's incredible and the animation is quite similar to Hiromu Arakawa's original artwork in the manga. (Not that, that has anything to do with it XD)
But if you have nothing to watch, go watch Fullmetal Alchemist Brotherhood it doesn't matter if you haven't seen the first anime just watch it and enjoy the awesomeness.
