we've been watching it for years. And for those who don't know it, you should try to watch from the beginning as it makes so much more sense when you get to know the characters.
I'm not sure if Doc is on netflix or not. But the entire series of MI5 is on netflix. You just have to call it by it's proper name. In Britain it was known as "Spooks". There
are at least 10 years worth of shows.
Another one to look up is called "Luther". It's a cop show as well with flawed characters that are so interesting.
