I think I like The Unit more than any other TV series I've ever seen, with the possible exception of a couple of seasons of 24. On some levels though, I even prefer it to 24, and that's saying something, as I do regard 24 as being at the very top as far as TV shows go, and although 24 is probably slicker and better crafted than The Unit, and more likely to be popular with a wider audience, I'm still drawn to the realistic feel that The Unit has, and the fact that it's not overly dramatic or totally blown out of proportion for the sake of entertainment, but actually tries to capture and express something fairly real and credible and with respect to the real Special Forces.
I didn't expect much from The Unit back when I started watching the first series, but little by little I have come to respect it, and now at the end of series 2 I can clearly say that there's nothing else out there that I'd rather watch. I do have a strong interest in and respect for the Special Forces (foreign and domestic), and the military in general, so obviously The Unit is right up my street so to speak. If you don't have an interest in such things then you'll probably not be quite as appreciative of it as I am, but nevertheless, interested or not, it's still an engaging and often tense and exciting show.
My favourite episode from The Unit is still from the first series, called 'Dedication'.
I thoroughly recommend The Unit to everyone, especially to those who have an interest in, or respect for, the highly skilled and self-sacrificing elite soldiers of the world, and the military in general.
I have no idea when series 3 will be out, but I certainly look forward to it!
