*A Japanese government endorsed loli-pantsu anime.*
Please don't say it is bad just because you find girls in panties horrifying. I admit it is lousy for the director to claim that girls in panties = fashion in the Strike Witches' world, but that alone is no reason to give a bad rating to an anime (if you do, I am sorry, you don't know how to rate at all). Strike Witches is MUCH deeper than one may expect to find from a fanservice-oriented series.

The Japanese Agency for Cultural Affairs has recently openly endorsed Strike Witches as an example of cultural excellence.
The world of Strike Witches is pretty much parallel to our world up to 1939 (before World War II). At that time, mysterious beings known as Neuroi invaded Europe. Thus rather than the real WWII, this resulted in a war between Human VS Neuroi. The story revolves around a group of girls with special magical powers that allow them to equip the "Striker Units" to combat the Neuroi. The story proceeds nicely with these magical girls fighting Neuroi, but sadly the ending seem to be a bit "wishy-washy".
The art and animation quality is great for the most part. The battle scenes, in particular, are extremely well made. In short, we see a nice blending effects from the battle animation with the regular drama scenes. All episodes seem to have highly consistent animation and of course, the DVD includes polished artwork and fanservice.
The OP and ED are both good although not particularly outstanding and there's a good chance you'll forget about them after a few days. However, the melody of the songs suit the theme of the anime quite nicely. In addition, the battle themes and the Japanese version of Lili Marlene (a famous German love song that was popular during World War II) all contributed nicely to the series and are valuable assets to the show.
The production group did a nice job at introducing the main/supporting characters and then slowly further develop them. Actually, the character introductions might explain why the story started out slowly (after all there are 11 girls to talk about). If there is one thing I find the characters disappointing it is that some of the witches' specialty were not revealed until the end (most were never mentioned).
Though I didn't like to see girls showing off their panties the way they are done in this anime, but putting that aside, the show itself (from story to art to sound to character) is very well planned out and the fact that they include references to the real WWII is just that much more interesting to watch. (*edit* The ending was really surprising, hope you'll enjoy the show just as much as I did)
