Full Metal Alchemist: Brotherhood is a retelling otf the original FMA. Many of the beginning stories are very similar if not identical, however it begins to completely rewrite the story as it goes on. All of the same characters are present and most have the same personalities. The animation is as good if not better than the original and the storyline is far superior in my opinion. I am a very big fan of the original FMA, and have re-watched it several times. Even though I believe Brotherhood is a better story, I have to show some respect for the original and how groundbreaking it was. This anime is well worth watching for anybody who was a fan of the original, however I suggest that you keep an open mind when watching. Like I said, It starts to become drastically different from the original and some hardcore fans might not take kindly to that. Other than that, please enjoy!
