This set does not include Live Another Day (there is an updated set that does) and while some of the individual seasons are available on blu-ray, the complete series is only available on DVD. The set does include all of the bonus content that was released for the individual season sets. That includes hours of deleted scenes, behind-the-scenes featurettes, commentary tracks on select episodes, and more. I definitely think the series did try to hang on too long. I think it would have stood up better if it ended after 4 or 5 seasons instead of going 8. Like many, I think that the 6th season was the weakest of the group. While seasons 7 and 8 did help the series recover (as did the mini-series, Live Another Day, which aired in 2014), I do think it was a show that would have benefited from a shorter run, especially since there was talk of a possible movie long before the series ended. Overall I think it was a well-acted, well-written series that was (especially at the beginning) very addicting. It did take a lot of suspension of disbelief and you have to be willing to accept some eye-rolling moments, but on the whole, it was a very entertaining series.
