[EX Q]: This thing is a major piece of junk. It doesn't stick to the wall like it claims. You have to stand to play with it (cause all the cool stuff is at the top), and the extension pieces constantly fall off. I actually screwed it to the wall, but that lasted a whole 10 minutes as it wouldn't stay screwed into the wall. Then the scenery kept falling. Save your money and buy the cool batmobile or something.
[EX A]: Negative

[EX Q]: I did not really care for this book. I found the plot messy and muddled, with many clumsy devices and scenes that felt forced (the climax, in particular, seemed very rushed, cinematically speaking). The characters, for the most part, were thin - and perhaps the author reached too far in casting the reference-net. I wanted to like it (I very much enjoyed Alan Moore's tales of the Extraordinary Gentlemen's League)... A very intriguing idea though (I give the acorn a golden prize but the oak grew sickly)... Maybe it is your thing; it was not mine.
[EX A]: Negative

[EX Q]: Sure this is an interesting book. Unfortunately the copy we received was written in spanish!
