Here's my top Nolan films:
1. Memento
2. Batman Begins
3. Prestige
4. Insomnia
5. The Dark Knight

All are great films, but I thought TDK had a couple of things I did not agree with Chris's work. Either way, it's still a great film.
I have not watched The Following though...

I think the book and the film are just too different things that share some similarities. I like both the book and the movie and I think both stand independently. There are creative and clever differences Chris Nolan makes, but I think that simply is because it's a film format versus the book format...

I didn't know there was one...
