Since I found the original FMA's ending so dissatisfying, I worked up the nerve to watch Fullmetal Alchemist: The Conqueror of Shamballa (or however you spell that) with a sinking feeling that I'd be wasting two hours of my life. Well, guess what? I was right; I wasted two hours of my life.
At least when I watch "Brotherhood" I can do so with a clear conscience.
