I like it. In fact, I don't think I've missed a single episode, but that's because it follows Fox's Sunday night cartoon lineup, probably--I seldom miss those.
The underlying premise, man isolated and alone, has been done many, many times before but handled in a humorous vein on Last....
And you can start watching anywhere along the series and pick up on what's going on fairly quickly, unlike Lost, which is what you were should you miss an episode...lost...forever lost.
