Nothing but superlatives across the board. I would give this series a 100 if the site let me.

It's probably one of the most interesting and deep manga I have read so far. It's fascinating, the interplay of good and evil and the decisions people have to make as they walk between those extremes.

I think most of the characters are super likable (especially Ed Elric and Roy Mustang!) and even when they're not, they're at least interesting. The sins (Gluttony, Greed, Envy, Lust, etc) are so damn interesting. Art is fantastic. All the characters look DIFFERENT and all the fighting scenes are well down.

Another thing I'm impressed with is how TIGHT the writing is. Not a single wasted page and a story that was very clearly developed with a ton of thought and planning. As I read through the manga, I kept going back to previous chapters and seeing old scenes in a new light going, "Ah! So THAT's what that was!" Some of it blew my mind, I'm serious. The ending was just so perfect, it was EPIC. Just the way that everything came together, ahhhh. Story is so good and complex that I've re-read it a bunch of times and came out appreciating something new each time.

It's a perfect story. Lots of complex themes. And also despite how dark this story really is (I mean, there's stuff like genocide...), there are many funny moments. They mostly come from Mustang and his crew or Mustang fighting with Ed or Ed's complex about his height haha.

As far as completed manga go, this one is my favorite so far. It's hard to reach this level of perfection in manga, but this one does it. I give it my highest recommendation. (Also the anime FMA: Brotherhood follows the manga very closely and is basically AMAZING. Watch it!!)
