I am a huge Kubrick fan. While FMJ and The Shining are up there, a think that they are not his best. A Clockwork Orange, Lolita, Dr. Strangelove, 2001:A Space Odyssey, and my own quirky favorite, Barry Lyndon were his best work. Not a bad body of work, I would say.
All those movies you mention were good, but Lolita was the only one not as good nor better than the book.
