well said.
I got into it last summer when the first season came out on DVD...all of our friends were into it already, and I had the same reaction (I loved 24, but felt...what's the deal? seems weird. ) Totally suspect.
Then, one hungover Sunday, we put it in at 10am......and, then did not leave the couch and watched 13 episodes in order...it was like crack...finished it two days later...and the obsession began.
It's like the rest of the ilk...24, buffy, alias, etc....all of which the people who don't get into have no freakin' idea why people watch them...but, once you're hooked.....you're in. Very, very creative, intelligent, well-written, well-thought out, clever, many layers, etc. etc. etc.
