I haven't read those yet, but I intend to. And I expect that, like every one I've read yet, they'll be solid 7 or 8 out of 10 books.

That's the thing that reminded me of Crichton. He has that same ability to start with some fascinating idea and run with it and deliver a solid, well-told and satisfying story, then move on to some completely different fascinating idea and run with it and deliver another solid, well-told and satisfying story. He's not locked into any specific genre or any specific approach to telling a story - just whatever works for that idea, that's what he does, and it just works.
