I'm way behind on the manga, but I'd just like to note a few things.
I hate it when FMA is mentioned in the same breath as other shounen series like Bleach or Naruto, because it fixes everything they do wrong. Terrible female characters? Not here. I especially love that Winry is just as talented as Ed and Al, but in an entirely different field. An illogical or completely unexplored political world? Nope, it's fully developed and intriguing. Attempting to up the ante with boring, meaningless powerups and interminable fights? Nope, here they twist things up with SCIENCE! and new techniques and emotional turmoil. Superbeings so powerful that they're gods compared to civilians? Very rarely and it's actually treated that way and properly explored.
Fullmetal Alchemist rules.
