I was skeptical of this movie, to say the least. As a huge fan of both animes and the original manga, I doubted that Fumihiko Sori and his crew could do Hiromu Arakawa's masterpiece any kind of justice.
However, the end result is surprisingly okay. Sure, the CGI tends to be an eyesore, the acting is all over the place, and some characters aren't remotely similar to their badass manga/anime counterparts (here's lookin' at you, Riza). But on the whole, this film kind of works. The screenwriters made good choices in terms of what to adapt and how to fit it all together, and some characters (mainly Hughes, portrayed by Ryuta Sato) work really well.
Most importantly, the film has heart. I get the feeling that Fumihiko Sori and c:o genuinely cared about the adaptation, and that ain't nothin'. It's an ambitious production, though arguably an overly ambitious one.
FAR from a perfect adaptation, and nowhere near as good as the animes or manga, but it's not an insult to the original story, and not a bad way to spend two hours of your life.
