The more I watch this show, the more I'm impressed. If you like James Bond movies, and you haven't seen the original I Spy television show from the '60s, you should. Robert Culp and Bill Cosby (in the first lead role for a black man in a prime-time TV series) are super-suave, capable secret agents. The show was shot overseas in exotic locales, has a hip score by Earle Hagen, and throws some worthwhile thinking into Cold War spy biz plots.
The first two seasons are now up on Hulu, so you can blaze through the whole set.
If you watch on DVD, you'll also get commentary from Robert Culp, who had an impressive TV writing career (working for Sam Peckinpah, among others) before the show, and wrote eight episodes for the first season. Listening to his story is inspiring for writers of all stripes, and especially for those working on scripts.
