Domestic debut: October 4, 2003

One of the great, irreconcilable debates of contemporary anime fandom is whether Fullmetal Alchemist: Brotherhood, a popular series that debuted in 2009, trumps the original Fullmetal Alchemist series that aired just six years earlier. I've only watched the original FMA, which happens to have been the last, true, international anime megahit when it took off in 2003. In both versions, Fullmetal Alchemist is the story of Ed and Al, two brothers in pursuit of a philosopher's stone that's key to resurrecting their mother and repairing their own disfigured bodies. From what I understand, FMA's Brotherhood reboot simplifies the series' antagonists, complicates the rules of alchemy, streamlines much of the earlier plot—all in deference to the original manga, which the original anime series outpaced and, eventually, eclipsed. —Justin Charity
