Season 4 of 24

I got thru five episodes of Season 4 of 24 before I went into work today and the show continues to impress.  I'm not happy that neither Tony or Michelle have made an appearance yet and I don't like President Keeler at all or the new CTU director.  I still cannot believe that I've missed out on this show for all these years.  I hope to be completely caught up and download all the episodes for Season 7 off ITunes by the end of March.  We'll see if that happens.
