Once upon a time, in a distant eastern nation, a pure masterpiece adapted from a popular manga work, those guys working in the Anime industry decided to adapt those illutrations into moving pictures on the small screen. The result: One of the peaks in anime history.
I'm not sure which part of the series is represented by "Part 2", and since there's nothing on RT for the original series, I'm putting time in for both.
In a similar fashion to the first two "Alien" films, the two separate series of Fullmetal Alchemist were as different as Bush and Blair, but there's no denying how they packed equally powerful punches, though in different spots.
The original series, "Fullmetal Alchemist", had it's roots as a modest, emotional-massage, with occasional action that jerked your senses head-on. It's successor, "Fullmetal Alchemist: Brotherhood" took more from the manga and gave us more of a whoppingly intense plot, filled with nice twists, turns and feelings of pure majesty that most anime fail to even skim.
Personally, I prefer to acknowledge the second season over the other, as the ending satisfies me somewhat more, though the original ends no less masterfully.
The characters remain faithful to their counterparts in both series, mostly, though their roles can differ spectacularly. What I love about them all, really, is how they manage to either be sinful badasses, or sappy maidens, and yet you can't help but adore each and every one of them, right down to the main antagonist.
All that given: a great big thumbs up to our favourite midget with automail prosthetics: Edward Elric!!
