nellorat's recommendation reminded me of the recommendation i would like to make: Continuum. For the time travel fans, it's a story of characters pushed back in time. There's social commentary: the crux of the plot is the initial sentencing of a group convicted of terrorism, and the context of the terrorist action becomes thicker and complicated over the season. The "kill your own grandfather" paradox is handled in an interesting way: it's not clear if it's ever quite resolved. Relationships are interestingly complicated, and it is definitely a series designed to be consumed as a serial.
I devoured the first season far too quickly, and i'm delighted to a second season is listed on netflix. I will not click past the "2" in order to avoid spoilers.
