So, um, ist das gut?

In January, the German translation of my book Death from the Skies! came out. Over there, it's got the cooler name Tod aus dem All, and has a cool cover, too. I was wondering what people in Germany thought of the book, and (because my three years of German classes were a while back) even after seeing this young man review it, I'm still wondering: So, um, is this good? He keeps holding up the book; does he want his money back? I hope not, since the guarantee on the book is only good for 10^92 years, or until all its protons decay, whichever comes first.
