Odd, since from most accounts it was a major flop. Then again, lefties are an emotional bunch.

I thought the story was compelling, but poorly executed. It was about how people were coping with the country ten years after the invasion, so there wasn't much action at all. The Soviets were finalizing the dismantling of our government, but the story mainly followed a set of characters leading very different lives. One wound up in a concentration camp, one was a Party member who had access to banned material and got to see how conformity was being forced upon everyone, one was trying to put together a fledgling rebellion, etc. The story was 90% vignette character development, and a lot of people found it boring.
I just went over the IMDb comments and one thing someone pointed out was that the invasion took place in the first place through political corruption. Basically the Soviets backed certain political candidates in the US and eventually gained enough of a critical mass that their guys over here effectively signed the country over to them (since the story takes place ten years later, it's vague on it but apparently there are outtakes that explain more). In light of the mess with Clinton and ChiCom funding I can certainly see why (ahem) certain people on the left might not want people reminded of that tactic and what a "successful outcome" can entail.
The series was also very clear that the UN was totally complicit in the whole thing and essentially put their stamp of approval on it to make it seem legitimate. Would never happen today with us running the show, but a good cautionary tale if you can get past the boredom (and the fact that it's *really* depressing).
I have no desire to buy a copy from the sites online as I've already seen it, and taking a second look at them makes me suspicious of their legality.
