A lot of TV shows are either finishing their run, or will begin to end.
Breaking Bad finished up. I'm on season four, so shhh.... Mad Men will receive a final season(s) much like Breaking Bad.
Boardwalk Empire has been renewed for a 5th and final season (I'm not sure if that counts as 'cancelation'. I'm guessing no, as it has been renewed. To me canceled is if word is being waited on, and the network decides 'no'.) I have yet to see season four, however.
Also on HBO, The Newsroom will get a third and final season. I haven't seen an episode yet, but it's a show that interests me.
And let's not forget that Dexter ended...even some of us rather would.
I guess TV shows coming and going is a sign of age, and the passage of time.
Aside from Breaking Bad, I'm currently watching Hell on Wheels and Homeland on Netflix. I also need to see season 2 of Downton Abbey, season 4 of Boardwalk Empire, and season 4 of Walking Dead.
What do you watch and suggest that's new?? And what would you consider some network's 'flagship' shows? With Breaking Bad and Mad Men to be off AMC's list, the go-to series on that network for me would be Hell on Wheels, for instance.
