I already have bought and watched it, despite being warned by some not so friendly reviews.
I knew beforehand about the character changes, and it didn't bother me - in fact, I thought that they could be interesting. I hoped that the entire thing would at least qualify for the "mindless fun" category of entertainment.
It doesn't. There are a few interesting ideas, but they don't get any development. The mini series has neither heart nor brain, but one has to admire the courage of the creators for putting something so dull and lifeless on the screen. To be fair, there are some nice moments, but mostly it is the typical uninspired SciFi production that does drag on and on and goes nowhere.
On the upside: I finally have something to show if I get asked about the worst thing in my collection...
