Wow that is big news, I did not know that! That book is so cinematic already, it leaps off the page. Should translate to the screen very well. Hope they do "Use of Weapons" and "Player of Games" also, in fact the entire Culture series is an amazing opportunity for TV conversion.
Excession stood out in this regard, until it didn't.
(Consider Phlebas also stands out, but it's a unique culture book by a mile)
Thats because it's not primarily about the action but about the technological, social and societal issues and conflicts. For me at least.
BTW. No spoilers please - I'm re-reading in chronological order.
Philip K Dick's Do Androids Dream of Electric Sheep is another great example; the book and movie are vastly different, yet both stand on there own and one could argue are great for different reasons. I'd be hardpressed to pick which I love more.
I do agree with a lot of what you are saying about Asimov's Foundation series; however I think the core ideas are what they'll focus on and most likely they'll introduce a host entirely new characters when they rework it as a screenplay.
Maybe a better/clearer point is this: I think Foundation is actually more suited for this kind of treatment because of it's 'flaws'. Aka, the idea is great and the potential is there to make it into something successful.
Of course, we'll have to wait to see if Apple/the production company can pull it off.
On a side note: I wish someone would buy the rights and reboot Babylon 5. I'm going through it with my GF for the 4th or 5th time since it aired. Still one of the best SciFi shows ever storywise and I have a soft spot for those Amiga VideoToaster graphics. Plus Vorlons.
And it likewise works OK for the characters to not be fully fleshed out immediately - they aren't on TV either, as the actors and writers get used to the characters.
Depending on how they manage it, this might not be all that much of an obstacle. Cloud Atlas faced the same problem, but I thought that their use of an ensemble cast to tell a story that spanned the several centuries worked out just fine.
Banks' "Consider Phlebas"
It's criminal that Banks never got to see his books as movies/series. Banks is, hands down, my favorite scifi author, so I hope the adaptation is well done.So they're adapting the worst Culture book. It's probably the easiest to adapt, but it's by far the least interesting.
...except for the last three, I think? They are a more typical epic space adventure that takes place within a single lifetime.
"She had a rough childhood (20 minutes of expose, plus mandatory flashbacks in every episode), her mom died when she was 9 and dad was a cheating alcoholic, but now she's a badass who will kick ass for the next 4 seasons. And oh btw look: she has a cool hoverboard and here's white platicky computers which are REALLY powerful. Also, some omnipresent AI will play God."
If you are not identifying with the protagonist, everything else is simply meh. OTOH, interesting ideas are interesting on their own.
I don't think there's anything wrong with having the setting act as a backdrop, per se. Stories set in the Wild West aren't about the technology of guns and cattle wrangling, stories set in the Middle Ages aren't about swords and battlements, so stories set in the future don't need to be about technological extrapolation.
Poorly written characters or a protagonist you can't empathize with is often the result of writers caring more about the tech and the technobabble than the human drama. Good sci-fi provides a balance of both - a plausible setting that doesn't explain too much, with stories that focus on the characters and their relationship with the setting.
There's not doubt that Asimov was pretty smart and there are a lot of interesting ideas in the Foundation books. However, I don't think that those will translate to the screen very well. Since the books span many centuries, characters come and go and are mostly not very fleshed out or interesting. Asimov is pretty similar to Lem in this regard, who also was much more interested in ideas than people. Of course, a good screenwriter can make up for that, but you can bet that people will be annoyed by all the additional stuff that is not in the book (like in Soderberg's "Solaris", for instance).
So I'm much more thrilled about Amazon developing a series based on Banks' "Consider Phlebas"...
