What I like about the Mad Max series and George Miller is that the language and behaviour of characters in each one is different/varied. So I was expecting the war boys language e.g. valhalla, shine supreme, guzzling of Fury Road to be throughout but it's not. And if you look at the original Mad Max the post-apocalyptic language and behaviour of the motorbike baddies is different.
Miller doesn't stick to any patterns. This is a spin-off so Furiosa's younger character is developed but you then have Pretorian Jack who's stronger than her. And you look at Immortan Joe and his sons and they're not the same as in Fury Road.
All of that as well as Dementus was done really well. I'll be looking forward to what Miller thinks up for the next one, and I honestly wouldn't be surprised if he goes left field again to the previous two because all the Mad Max go in different directions.
