I wouldn't call Storm Front or the sequel, Fool Moon, great books, but I am definitely a fan of the series. I started when I was a kid when the fan-service was just that--exactly what an impressionable young reader thought was awesome. What I really like about the series, however, flawed and cliche-ridden as it can be, was how Dresden matures as a person and a character (I think in tandem with Butcher maturing as a writer). If you like anything about noir or urban fantasy, the series just keeps dishing it out for you. :)
