I love a good crime/spy drama. And this fits the bill. I have never seen the movie but I reallylike the show.
Season 1 is kind of like a 10-episode-prequel to season 2. It tells the story of how Brian ended up working for Christina. His first mission, with his first team. Season 2 starts with a new team under new and completely different circumstances and where season 1 was one big story, season two is more like a procedural with a new "case" in every episode.
