I mean, they were more complex then your average blockbuster, but compared to a Lynch movie they're child's play and i like them apart from Inception. I never really needed to think too hard to know what happened in Memento, Prestige, Inception, Interstellar and Dunkirk, so Tenet is a first in this sense because you probably need to watch twice to connect all the dots.
And when i said visual effects, i didn't mean computer generated, i know his movies are the flagship for practical effects.
Yeah, when that user said the prior movies were balanced, what he really meant is that they were walking on the fine line between too complex and acceptable for general public, so this time Nolan made a 200M movie and at the same time gave a middle finger for the average moviegoer
