You're saying a lot of stuff, but not backing any of them up and also ignoring the wider context.

Also, with your last point, his more original movies tend to have complicated storylines and themes, one of the first thing we learn as filmmakers is to KISS, Keep It Simple Stupid because "your audiences are idiots".

Whilst I'm sure you're super smart to work out the theory of relativity, the majority of audiences won't understand jack shit about it.

Whilst you may be super smart to already know how lucid dreams work, the majority of audiences think that it's something made up by Inception and that it's all fantasy. I was actually surprised that no one I know believes lucid dreams are real.

Making movies isn't easy, the last think you want is the audience to think your film sucked cause they didn't understand it, which was a very common criticism when Interstellar came out. I should know, I used to work at the cinema and people would straight up say "have you seen it?", I'd say "yes" and they'd say "it's shit isn't it?", as if they're seeking confirmation that it's actually shit or they're saying they didn't get what they just watched.

It's the most annoying part of Reddit, "why do people keep treating the audiences like idiots?! We are super smart! WE UNDERSTAND", well yeah you do, but the majority of audiences ARE idiots.

Now yes, there are many films that are obscure, some incredibly pretentious, that require years of debating and analysing to figure out what it's about, but those films are aimed at a totally different audience than Nolan's. He's focussed on the masses. Those confusing movies, like The Fountain or Mr Nobody, that require heavy analyses to make any sense of, that's a much more niche market and it's aimed at an audience that have the ability to analyse movies and come up with their own interpretation. The majority of audiences do not have that skill and rate films depending on how much they enjoyed it.
