I watched it and thought it was pretty entertaining. A tip off from 24, which is awesome in and of itself.
Yes, these shows do not follow the true realism of what they portray, but the fact that this show is Pro-Military and shows a side of the military outside of the US (and in), doing what they do to protect our freedoms (as quoted from the show), I have to give it a thumbs up.
I mainly watched because of the lead guy. The shows seems to be in good hands, with him in the lead.
The ONLY thing I found disturbing, was the ending scene. I was so glad to see how supportive the wives were being to their husbands doing this "secret" job and standing by their sides, waiting at home for them, praying and hoping for their safe return to them, not to mention that I am really tired of seeing unfaithfulness on tv, that this scene made the whole show kind of a down turn.
However, I will still watch it and hold my opinions in check until after further episodes. If this is anything like 24 (as it seems to be), it's well worth watching!!!
