Just saw it. It was great.

The only three problems I had with it was that guitar and steering wheel shot, their reason for going back to the citadel, and their plan once they did.

I think it was a bit too easy to convince them that turning back was a good idea. Sure, salt flats are bad, but they seemed prepared to endure it. I would've liked to see something force them to turn back, or not try the salt flats at all. Very small quibble, but that may be just me.
Second was they seemed way too confident that the citadel would apparently be defensible once they got there. They didn't know they would get a chance to kill Joe, and even if the path was closed, the mountains could still be bypassed. I totally bought the people's reaction when they showed up with the "god" dead at their feet, but that should have been part of the plan somehow.

BUT other than that fridge logic, I thought it was great. As an action movie it was incredible. The violence wasn't body horror like I detest: just enough for you to flinch and fill the rest with your imagination.
The acting was great. Hoult, Theron, and Hardy were on point all the time. I bought the side characters too.
The fact that both the men and the women needed each other to survive was great. Not man-dependent or woman-power. Just people with strengths and weaknesses.

One final thing that made me happy: when Furiosa doused the burning engine with dirt, my immediate thought was "isn't that getting in the air intakes?"
...followed immediately by a shot of the air intakes re-opening their guard valves as the sand fell away. Perfect!

I got the sense that 160 days was just their way of saying "we have no idea how far."
They talk in mythological, melodramatic ways because of their society so it made sense to me.

Yeah, that was everything I love about movies, in one movie.  I feel like all movies are trying to pick up mjolnir, and George Miller just walks by and *yoink* effortlessly grabs it.

The world-building without exposition was by far far far my absolute favorite thing about it!!!
That the characters just did stuff and behaved in such ways that we were expected to observe and figure things out...it made me wholly engage with the characters. I bought every one of them and their turnarounds and motivations just by paying attention.

I think even without knowing anything about Mad Max, the movie works. So maybe it avoided exposition because it's a well-known franchise, but the result is the same: the movie works on its own.

The character had nothing to live for. He happened not to kill himself. The girl is what happened next.
