This is definitly one of the best shows i have watched in a long time, it seems to include everything you could wish for in a show. The storyline for this show is a piece of genius, however someone thought of this a do not know, it is original and at the same time great. Its not just the storyline which is great, the charectors created are marvelous as well, making the show brilliant. This the second and final series of the show which continous on from the fantastic first series which was just as good as the second. The series still follows Sam trying to get home, while still trying to understand why he is here in the first place. A must watch show for all.
