Seasons 1-4 were really great, I blew through them in a week and was totally hooked, but after that the writing went downhill unbelievably fast. Season 5 almost did me in but I stuck with it and I suffered through Season 6 just to see how it finally ended and it was excruciatingly hard. Walt became an utter cliche by the end, as did Vic, to the point that I really couldn't stand either of them by the last episode. Just so unbelievably sad to see a good show ruined by such horrible writing over the last 2 seasons. And the actual ending was so utterly ridiculous and disappointing I just had to write this review to warn people. Take my advice please, watch the first 4 seasons of a great show then STOP! Sure wish I had...
