The first season is a very extensive and amazing version of the movie. Of course there are parts added, but it is fully in the spirit of the movie, and very well written. The second season was a continuation of the first season, as if it was one ongoing story. However, about season III: wow. I think it's somewhat like the Godfather (comparison ends as is): part I is an epic tale, part II is rather good too, but season III is just the worst. What the f*** happened?! This is nothing like the first two seasons: the acting is (very!) cheap, the story is fully not connecting to the previous story, it's just... too simple. As if the budget was cut by 90%. This is like a new series trying to lift by on the success of the first two seasons. I just can't find the right words for how terrible this is... Like Scrubs: if you liked the first seasons, as I did very much, do not watch the last (/latest) season!!
