Loved it, too.
It was great to see Jack operating as he must have when he was black-ops. And not only was Maybourne (almost) sympathetic, but this episode made his character a lot more interesting. Another nice thing was that both story lines were intersting and really well done. It was fun watching Sam be a scientist again, and watching Daniel try to play office politics with Bauer.
It also had some really funny lines, like
Jack, upon seeing Maybourne's safehouse - Have you even HEARD of IKEA?
or
"How is that beer and mustard diet working for you?"
Can't remeber the exact lines, (paraphrasing here) but when Hammond asks what he can do to thank Jack, Jack replies 'Continued patience, latitude, and understanding sir....and one day I might ask you to buy my soul back". That was wonderful.
But I still haven't gotten over seeing Maybourne in a Hawaiian print shirt --- shudders!
