...can we reboot a few book series?
Loved Rendezvous with Rama (something that still needs to be made into a movie). The books that came after, not so much. The fourth book is cringe worthy bad.
The Foundation series, with the right author, could be continued. Not going to say that would be easy, but Second Foundation Trilogy put out a few years ago didn't really go anywhere.
I haven't read all of the Ringworld series yet, but I feel it hasn't aged quite as well. Maybe not a reboot, just some rewriting?
On the other hand there needs to be a stop to all the endless Star Wars and Star Trek novels being pumped out.
