I have to say too, about Nurse Jackie: the last couple of seasons have been pretty heavy-handed and I, like quite a few people, have felt like they should've packed it in. There have been some stupid sub-plots, awkwardly told. Weak comedy.
But at the same time, this season has gone in some really dark directions with the addictions. VERY authentic. No doubt they have addicts involved in the writing. The last episode had some great turns.
Season 6 finale is tonight and it appears that there will be a season 7.
It is just such a mish-mash. Some great stuff and some awful stuff. Prolly more heavily weighted to the awful stuff but as an addict they do come up with some stuff that makes me go, "Oh fok shit."
