I loved 24 when it first started, but tho I watched it when I could (don't have or want Sky) two things spoiled it.
Firstly, just how many incidents of exactly 24 hours can this guy have?
Secondly, the second series was set in the (then) near future, ditto for subsequent series, so by all accounts, the world of Jack is now well ahead of ours, and to me it doesn't ring true.
I used to buy the DVDS and watch them all in marathon sessions, but I'm not bothering now.
