I can completely agree with you that interstellar was really his worst work. It was zimmer trying to be zimmer. But dark knight and dark knight rises, especially rises, have so much more to their soundtracks. Even little things like catwoman's piano clink are well designed. You look at 1 main theme and it was massively popular and so many tried to copy it, but it also really symbolizes the feelings of the nolan trilogy. Pirates has so much more depth to it than the basic main theme; singapore, the kraken, and up is down ('sea shanty' sure but it's at least different).
