Anime — Magical Girl Lyrical Nanoha and ditto. A's

I tried this series out because of the on-going buzz about it on /a/, like —

It is made of high-speed, high-powered aerial combat, a touch of fanservice, massive explosions and major amounts of win. Despite the name, it's only a Magical Girl anime for the first three episodes of the first series. Then it becomes great. Then it becomes awesome at episode 7. Then it becomes legendary from the start of the second season.

and it did not disappoint. And if you need more inducement, there are also delightful magical devices speaking Super Engrish as well.

One of the nicer touches about it is that Nanoha is one of the more sensible, level headed, and yet nice characters around, from business-like talks with her parents when she tells them she has to go away and do her magical girl thing for a while, to the way she seriously befriends people. And by people, I mean Fate-chan, and then the Velka Knights from series two.
