Seasons 1-3 were quite solid. They were interesting, fun, entertaining, and thought provoking, with each character having an interesting plot line for the most part. Season 4 started off ok but quickly went down hill with its "and it was all a dream"-esque ending. The ending of season 4 had some of the laziest story writing I have ever seen. No show should ever end the way this one did, especially a show that was this decent. I understand the series had to come to an end at some point, but there are better ways to finish it off. Nevertheless, I would still recommend this series to others given that the main bulk of it tells a good story, despite the disappointing last season.
