MM2 is like Metallica opening for Ozzy Osbourne in 1986 still fast and raw but a little more ambitious.
Thunderdome is like a Judas Priest show, full of big budget pyrotechnics, still kick ass, full of denim and leather, but a little more melodic.
Fury Road is like seeing Slayer perform Reign in Blood at an all day thrash fest following Gwar!!

the evolution of the three MM movies almost exactly mirrors that of Metallica's first 3-4 albums from undergrond cult status to arena headliner during almost the same time frame.
Back in the 80's the most important movies to punk/metal culture were A Clockwork Orange and MM 1 and 2, along with Repo Man. At the local T-Shirt store is was not uncommon to see Max on display between Sid Viscous and Vic Rattlehead.
