Fast Paced with well choreographed action sequences. A totally different view on any TV series i have seen. Definitely keeps my attention. The two main cast member are strong with the side story lines developing at a good rate.
With the same idea as lost, the back story lines are told as flash backs, the makers have executed this really well. Not only are they few are far between so you actually enjoy what story is being told in that episode it also gives you dates it goes back to so you are not confused.
