This show blew my expectations out of the water. It has a rating of 7 here with extremely few votes, and approximately a 6.5 on My Anime List. It isn't the best anime I've ever seen, but it's a heck of a lot better than those ratings make it seem!
I'll start with the bad. Out of the many characters, only a select few get any kind of development or deep characterization at all. This goes for most shows, however. There is some serious yuri-bait, and while you wish some of the people get together, it's an anime that isn't solely centered around a single relationship so you know it's not going to happen. Some of the story elements are a little confusing, especially towards the end, but any casual viewer should be able to get the gist of most of it. The last thing is that there are definitely some cliche moments, but what else can you really expect from a yuri-bait, sword-gun, monster killing, drama, comedy, action anime?
I know I just said a bunch of things I didn't appreciate as much, but those things are FAR outweighed by the good in my opinion. First, the visuals are actually pretty good, I'd say a little above average. The soundtrack is downright awesome, and the op and ed are both really great! The story, while really just an excuse to get some cute girls wielding sword-guns fighting monsters, really lends itself to the characters and interactions it sets up. This show is still mostly just fun, but there are some actually really touching or moving moments. In one scene, I actually felt some tears welling, which was not anything I expected from this anime. ALSO, THESE CHARACTERS DEVELOP!!! And while it's really only the main 2 that have development, the development works really well with the story. Speaking of the story, the first bit is more lighthearted, and it gets slightly more drama heavy towards the second half. That brought down my rating a little, but then the show absolutely killed it towards the end, and even the drama and emotional scenes made the show better! The ending was good too, even if it was a little confusing. And while you can't really tell 100% of the time what is going on during the action scenes, it's just so damn awesome you can't really bring yourself to care about that little stuff.
Overall, this was just a hell of a good time. I'm sure all the reviews with low ratings have good reasons for it, but in my opinion this show more than delivers on what it set out to do.
