I guess I'm asking if the show has replay value or not.
I've watched most of the season 1 episodes twice (on blu ray).
For season 2, there's not many episodes I would consider watching twice. (Only ones I've been compelled to watch two times, were the first two episodes with Root, the final two episodes, episode #16 with the first appearance of Shaw, and episode #13 with with Kara Stanton being killed).
Overall, I thought the season 1 blu ray set had some rewatch value for me. (I didn't really watch season 1 in its original first-run broadcast).
Though I doubt season 2 will have much rewatch value for me, if I choose to buy the bluray (or dvd) set.
