It's also a largely character driven show. A lot of the show deals with tracking Charlie's development from you're average caustic cynical world-weary schmoe to someone who would be willing to give their life up to save the world. So if you're not interested in getting a healthy does of character development each week, the show might wear thin pretty quickly. But on the other hand the series features a healthy dose of corporate espionage, secret organizations, terrorist groups and assassins, a better than average villain in the psychotic-with-a-cause 01, cool future tech and a good old fashioned detective quality to it, so, while it's not a perfect show, it has its merits, and when you get to the end of it, if you make it to the end, you recognize it for the pretty impressive piece of television that it is.
But anyways archiguy, remember to thank your wife for me. At least through her I've managed to get one convert for this show from this thread. lol
