Just saw it.
Hardy is the titular character, but Theron is at least the co-lead if not the lead... and I'll mention that the subtitle actually refers to her character.
If you're a fan of non-stop action, 40K, car chases, car crashes, nonsensical gadgets, explosions, chaos, mayhem, destruction, and insane stunts... or if you're a guy, then you'll at least mildly enjoy Mad Max: Fury Road. The action puts everything by John Woo, the Wachowskis, Donnie Yen to shame.
My friend who loves action flicks was giddy throughout and after the flick. I worry he'll ram someone on the way to work tomorrow.
The setting is basically Stagecoach, the film that made John Wayne a star, at the speed of Fast and Furious, but the story is pretty close to The Last of the Mohicans. Hawkeye (Hardy) and Chingachgook (Theron) have to get the Monroe girls to safety. One of them falls for Uncas while Magua wants them all for himself. The entire movie is one long chase.
Hardy only had to wear a half mask for half of the movie this time.
If you don't need any plausible basis for the setting or the villain, if you don't need more character development than venting anger, if you don't need any more character motivation than 'because', and if you can just turn off your brain because the thrill ride gives a new definition to gratuitous violence, then go see Mad Max: Fury Road immediately if not sooner.
Don't get me wrong... I enjoyed it. It was big and fun without needing a reason to be anything else. FR is what Beyond Thunderdome should have been.
