You cannot watch 'just one' episode of this hour-by-hour drama (24 hours in one day, each episode = 1 hour (in theory - less in practice (sans commercials); 24 episodes in total -- you'll need to set-aside some time! You will find that that 'lets watch another one, its only 03h00!" becomes a familiar refrain! The adventures of Jack Bauer and the Counter Terrorism team supporting him are high drama - tight scripts, more than enough gadgetry (watch for the development of product placements as the series unfolds through subsequent years) and various moral dilemmas make the story intriguing. Character development is masterful. The DVD is the best way to watch 24 - I don't know how anyone could wait 'another week' to find out how we escape the latest cliff hanger. Enjoy.
