You know the big thing about Nolan? He is a director who pretends to be a pretentious one trying to hide it... which is a perfect analogy for his movies too. At least someone like Terence Malick is pretentious without trying to hide it, while many others (like Jodorowsky or Antonioni) can get away with it by actually believing in their own pretentions to make it at least sincere.
Nolan on the other hand is so calculating that it just makes it frustrating, like that infuriating ending to Inception. The movie already is so full of mile-per-second technobabble and plot exposition to make regular people's heads spin, so by the time they reach the "ambiguous" end they come out of it with the fantasy of having seen something actually profound. Then he's praised for being some fantastic genius, while I'd rather crawl to a corner and cry. Sometimes it's hard being an analytical film buff...
