Interesting. I liked the books although the first three are - as even Asimov admitted - people standing around in a single room and talking a lot. I imagine theyll shake things up a bit for TV.
I recently finished reading the main trilogy, and I would definitely agree with that description. Asimov's writing style is basically to put a bunch of people together in a room and have them converse about something that just happened to them. Then he jumps ahead in time after some other major event has occurred, and the characters have another conversation to explain that event.
Basically it means there is absolutely no sense of immediacy to the scenes at all.
But, despite that, I thought the books were entertaining and there were quite a few cool ideas.
I think it would work really well as a TV series. The storytelling style in the books is so sparse that there's tons of room for expansion and stretching things out.
