Hi, What do people want now days for goodness sake all CGI, well there is non of that in S.I.S l thought it was excellent, gritty, with a bit of character development, and what made it all the more real is that the cast was unknown (well in the UK anyway). I was a bit disappointed in the ending, but then l suppose that will happen in real life as well (not telling you what l mean as it would spoil it) The actor who played the bad guy was a real B*****d, and you really wanted to see him get his comeupance, l've seen a lot of TV series that could be cancelled and I just can't understand why they did not continue with the TV series, but anyway if you get the DVD enjoy it it's well worth a good watch l give it 8/10
