After thoroughly enjoying the creativity, grossness, and great artwork in volumes 1-3 of the Exterminators series, I was completely disappointed with volume 4. Where do I begin? The artwork was not of the quality or consistency that one would expect from this series. Simon Oliver's writing became downright lazy, relying on recycled 80's and 90's action blockbuster movie cliches, especially in the anticlimactic "action packed finale." Oliver and Ty Templeton seem extremely out of touch when portraying people of "other" ethnicities. They don't do well by women either. Templeton draws a 15 year old character who looks like a 28 year old supermodel. Oliver drops the ball with characters Page and Laura. There is very little, if any, insight into their characters. Their role in the story never goes far beyond them being Henry's current and ex-girlfriend-gone-bad.
Characters previously introduced into the series are forgotten or merely glanced over like Stefan, Nil's estranged son, who's mysterious criminal background is never explained. Saloth's romance, dark past, and potential legal trouble with Detective Hunter all seem to have completely disappeared.
To me, the insects were the most effective characters in the story. Their scheming and methods of devouring human prey were truly terrifying.
I would highly recommend that anyone who liked the first 3 volumes borrow this book from the library before you buy it. Otherwise you could have a rude awakening and wonder where your $15 went.
