I'd recommend reading his Kurt Sutter's blog, I think I posted a link somewhere earlier in this thread. From what I recall, he's always been very complimentary to FX and the freedom that they grant. He also explains (without spoilers) that he's very cognizant of the direction he wants the show to take in each season.
It is definitely worth a read.
Thanks for the recommendation, I actually checked it out a little from your earlier link and will do so again. Sutter would know a lot better than I and it's possible F/X is in a lot better shape these days, thanks in part to The Shield but also many other edgy programs. (most I have not seen but am aware of and know to be running multiple seasons)
I was thinking about The Shield commentaries and stories about how season 4 or 5 would be the last, getting mid season extentions and other issues like A-list guest actors and their contracts. I recall Forest Whitaker's character coming to a very abrupt, though satisfying end due contract conflicts. (possibly exacerbated by the writers strike if I recall correctly)
Anyway, I added Sutters blog to my favs.
