At a certain point, when you decide you're going to review every volume of a book or manga series that has more than twenty volumes . . . you run out of things to say.
I've reviewed twenty-one volumes of Fullmetal Alchemist, and I have nothing left to say. I could reiterate how much I love this character or that character, or how much I hate that other character, or how much I want to be an alchemist, or how awesome the cover is, or how nasty the villains are or how much I love the humor, but it wouldn't be anything new, because chances are I've already said half of it at least ten times.
So, I'll sit here and say nothing, and I'll just be generally in awe of everything that has anything to do with Fullmetal Alchemist.
Except for Hohenheim.
