Overall, I thought it was pretty good. However, I wish they did explain more things (strange words, relationships, etc.) because I have never read the books and I didn't feel like re-watching the first mini-series again just to get caught up.
Like you A_Ranger, the third part seemed to drag on forever while the other two came to an end faster than I expected them to.
It was nice to see SciFi produce something with quality! An oxymoron I know.

I thought this was a more worthwhile project than Taken which I could only manage to get halfway through.
BTW, I am glad someone mentioned the spoiler issue because I had to stop reading after a while since I had only seen the first part at the time.
