It's a do-over of the Full Metal Alchemist anime series that is closer to the original manga than the previous series.
Now I haven't read all of the FMA Manga, but the episodes that I can match up with the manga have all been excellent. The animators have brought in more of the characters from the original work like:
Lin Yao

I love this guy!

Lan Fan

Also awesome.
May

Huzzah for little girls who kick butt.

There are several more that have been a genuine joy to watch, but I'll leave it to you to find them for yourself.

I give it the full five Flamming Croissants of DOOM! out of five.
