Just finished the last episode right now (and the series)
I don't care what anyone else says; the show was brilliant, engaging, witty, funny, emotional, and well made. It was always a step ahead, and Aaron Sorkin is a genius.
The acting was quite good all around, the writing top notch, the direction fantastic, and it all meshed together to produce an excellent product.
People can bitch and moan about the skits on the (fictional) Studio 60 show not being funny (which, to me, is rather like complaining that Dunder Mifflin's employees don't do much more than pulling pranks on each other, planning parties, and dealing with Michael Scott's love life and life issues) but that's besides the point; it's really just background filler material, and what happened otherwise in the show is what needs to be focused on. That's a lame excuse to dislike this show, and it's silly, seeing as how the skits accomplished what they needed to accomplish, and were featured very minimally as it is.
One more time: I don't give a damn that it didn't find an audience (since when is that indicative of being worthy of one?), and I don't care about the jagoffs who come online and bitch about tv shows and movies they don't have half the talent it takes to produce -- this show was fantastic in every way.
