It's a nice anime. ^_^ It follows a boy and his brother on a journey to fix a mistake they made as children that destroyed their lives (well, I guess the loss of their parents really started things, though). If you compare it to Frozen, then the older brother (Ed) is a bit like Elsa (...only he's not as quiet and polite as her), and the younger (Al) is like Anna (except not as clumsy). But, instead of Ed hiding from Al, Ed feels the need to make things up to Al for his mistakes, and would do anything for him. Also, Hawkeye is one of the characters that the brothers interact with somewhat often.

There's actually two versions of FMA. The 2003 version has 51 episodes and a really pretty art style. While the second version (subtitlted "Brotherhood") is newer, follows a plot that's more similar to the manga, has quite a few more episodes, and has a rougher art style. My favorite is the 2003 version, but Brotherhood isn't bad either.
