I prefer to call it "Goshiku" since that's what the kana says (and the word Gosick makes me think "go sick"... leading me to feel better calling it Gothic, since that's the common pronunciation of those kana)
Anyway, I love this series. I think Victorique is absolutely adorable, even in all her boredom and precociousness. And... I think she's more like Mycroft than Shinichi (or Sherlock). The back story between her and the detective surprised me, and I'm a big fan of the dynamic going on between her and Kujo.
