I watched eight episodes of FMA brotherhood and thought it was garbage. It has god awful pacing, they only devote two episodes to greed and the devils nest, when they should have done three. Not only that but they mix up the events and changed several parts too. The animation is terrible, some of the laziest shit I have ever seen, it especially annoys me when they use comedic scenes to cut down on the work they had to do.
ex. When Ed and Al are escaping from father Cornelio, they use the "comedic effects" to reduce the amount of time they needed to animate, not only was it lazy but completely clashed with the tone of the story a few seconds ago.
This happens as well in the Leeto ark, when they turn father Cornelio into a giant monster thing even after his hand gets fused with the machine gun. He is supposed to be on the ground screaming in pain, but instead he shrugs it off and doesn't seem to notice just so they can pad out the time.
Voice acting is still bad,I don't know why they kept Al's voice actor, he wasn't good in the original, and he isn't good now. Several other voices are very questionable including Greed.
Brigadier General Bass Grand's death...sigh... I could go on and on about what is wrong with the series, but I wont.
All I see is a shitty cash in that does the manga less justice than the original.
