Very much so with Pern, although I find that certain details that haven't aged well about the culture (and implications of that culture) kick me right back out of the narrative. I am biased in this regard, in that I'm re-reading and commenting on all the ways that Pern hasn't aged well, so I'm predisposed to find those spots. Someone who is there for the dragons and doesn't particularly care about the world around the dragons will be entirely satisfied with the series.
