i'm stopping any hyperbole here because i don't want people who don't enjoy it to come back and say "zomg you said greatest thing ever" when it's not my intention to GAF this movie.
i'll just say this:
1) it's not a mad max clone, though road warrior along with many, many other 80s films figure largely into it (to list them would be to ruin surprises)
2) i found it quite enjoyable and well worth my full priced evening showing money.
3) many of the people walking out of the theater had big goofy grins on their faces and excitedly discussing scenes
there are strong elements of british comic book / science fiction sense of "cool." It's not guy richie or anything else like that. it's rather more tank girl or the like than an attempt to emulate american action films (though not the horrid tank girl movie)
it was to me, just a great, fun film. not for everyone, but it was certainly for me.
