"Halt and Catch Fire" is a really good character drama. here is a corny trailer that does not do it justice I believe it is still on Netflix. Not leftist, but does a good job portraying the cutthroat and unethical behavior which is prevalent under captialism.

"The IT crowd" is pretty funny, also on netflix. Kind of veering into The Office territory though.

As libbed up as it is, I really like "Curb your Enthusiasm"... usually solid comedy.

All of the Star Trek series. (DS9/TNG are good entry points... TNG would be ideal, but it takes a couple seasons to really settle in). I believe they're all on Netflix, except the 3 most recent series (currently running shows)

"The Wire" is a good show from a writing and directing stand point, but it is definitely filled with copaganda and anti-union sentiment.
