Welp. To bring new life to this thread, let's start a discussion yay!
Actually, I finished Fullmetal Alchemist Brotherhood today and this is, by far, my favourite anime of all time. The story was amazing. It was deep, emotional and at some points hilarious (referring to Ed's shortness). It could easily change the point of view for several people on subjects like life itself though, so I wouldn't advise it to kiddies. The intro's and endings were amazing. Not only did they have great music, but they also tell the plot and what's going to happen in the coming episodes.
The characters themselves were my favourite part. Mainly because literally EVERY character had a purpose within the story. If one would be missing, the entire plot could change. Even silly Yoki had his important moments. And the personality of most characters were great too, to the point where you become sad and tears roll out of your eyes because they turn out to be dead or missing in any way.
I loved this anime, I could easily watch it again and again and again... But I don't have any time for that due to me always being busy.
Oh, and Brotherhood even gave me a new favourite Japanese song:
