I watched Justified for 6 episodes, like James Ellroy's stuff, and heard he wrote and co-produced that series.
And Swag, totally spot on, obviously. But as I said earlier, I realized around middle of season 5 that they would really not bother answering these things, even if I am still shocked by the cheesy cop out ending, because they can still end it in a way that is not that lazy and meh without answering much to us.
Ken, I like 24, but its no where near Lost's level (even if extremelly well produced), been way too inconstent or one sided (there are several series better then 24). But yeah everything Jack Bauer related is awesome

And dont fret, 24 will have a movie coming out.
Ken, agree with above mentionned series, can add Sons of anarchy, interesting biker gang crime series. And Supernatural, very unique series.
And pretty much you should try everything in HBO's catalogue

Except Sex and the city

Usually high standard, The Wire and Rome being the best IMO.
