Memento was his breakout film and still holds up well. Definitely 9/10 for me.
The Prestige was pretty good.
Dunkirk was ok.
Interstellar and Inception are waaaaay overrated. Nolan attempts to use confusion to create an illusion of "depth".
The Dark Knight is good ONLY because of Heath Ledger's amazing performance. This time, Nolan attempts to use "dark & gritty" to create an illusion of "depth", but it's littered with plot holes and nonsensical behaviour by Batman. The only thing I'll rewatch is a Joker montage on youtube.
I'll be watching Tenet this weekend. I sure hope it's not another attempt to confuse viewers into giving it a good review, although I'm half expecting it to be.
