The best Clancy novels are his older ones. The ones that became movies barely resembled the books (the books were very good); Without Remorse and the Cardinal and the Kremlin were his two best. The main problem is his best books are very dated now, because they were written 25-30 years ago.
He apparently wasn’t even writing the Jack Ryan universe ones after The Bear and the Dragon. His last one was a near scene-for-scene storyboard for most of the movie Act of Valor.
