Just my $0.02 worth...
It's a great movie. But... it started too quickly and I spent the first 20 mins doing the "eh? what? errr... eh?" After that, it all kicked off and I didn't really care as overall it's a huge mad beautiful looking utterly bonkers mayhemic firecracker of a movie.
You could replace Tom Hardy with any generic male action lead and you wouldn't notice. They should have called it "Mad generic post apocalyptic bloke."
It's Charlize Therons movie. I love Charlize Theron.
