I read Serpent's Tooth today. Honestly, it was pretty crap. I did like the art, and given that Moench penned it, I was expecting it to be good. It was too ridiculous for me and he was trying too hard to get puns in. The bad jokes are an aspect of James Bond, but it was just constant and they were awful. I actually struggled to finish it and its only three books, which I think was about 5-6 issues worth. Verdict - read it if you get the chance, but I wouldn't bother hunting it down or anything :P
