Watching the DVDs
I'm impressed at the amount of story they were able to work into 30 minute episodes. Shortly after the series, Vaughn expressed some dissatisfaction with the scripts, which years later he thought better of.
Personally, I think most of the scripts are interesting, and a few are quite amusing. Of course, the characters don't have nearly as much dialogue as in a 60 minutes show, which may have helped him form his early impression.
