As with a lot of things, expectations going on can have a big impact. I honestly didn't expect much. Most of my reading list is populated with nominees and winners of the major SF&F awards, plus articles/reviews from sources I respect. I post my notes about everything I've read (these "mini reviews") here annually, and sometimes those posts get a lot of comments. DCC came up a number of times as recommendations by folks here, but of course I don't know any of them or have any history of what they consider "good." But it came up enough times that, though somewhat dubious, I decided to give it a try.
I liked the first one enough that I've continued to read the series. Like I said, it's not the deepest of most innovative thing I've ever read, but it's fun and I always look forward to the next one, though usually I want something else in between.
