I haven't watched all the episodes, but just for watching few of them i can tell that FMA is just a really sad history, i feel pitty for Ed and Al, special Al who has lost all his body and he can't feel anything. Ed is always trying to make feel better his little brother, and i's funny the way he get's nuts every time someone calls him Shrimp (jajajaja). They are just kids, and they already have passed very hard times. but being together makes them strong.
