The only clear fault I've found in this anime is some of the characters(mainly Reika and Silvia) Silvia is just plain annoying, and Reika's attitude seems too childish and it isn't exactly beneficial to have a dark/emo character always moping around.

Other than a few rageworthy moments with the incompetence of those two, I wholeheartedly suggest you watch this anime. The ending is great(and for the sake of not hinting at the outcome, I'll leave it at that.) It didn't leave me with any bad feelings towards it, since the two lacking characters made up for their folly in the end. Definitely worth the watch, though you may find yourself not liking some moments with Reika/Silvia. Only my opinion though, so you may actually like them once you get into it. 4/5 because of flawed characters. Otherwise excellent.
