I honestly have to say that I'm not sure if I've ever seen another series this entertaining. It has the slick feel of a movie, with some twists that even good movies can't compare with. I was repeatedly exasperated, shocked, and fearful for the characters.

Don't be fooled by some people's comments that implied the "real-time" gimmick is what makes this show innovative, because it's actually just an incredibly well done series. The idea that the series takes place in a 24 hour period simply heightens the intensity.

Buy Season 1 on DVD. It makes my other favorite series (Oz, Sopranos, X-Files) look slow.
