This turns on the comic incongruity of a prim and proper country lady (Blethyn) venturing into the high end dope-dealing business after finding her late husband has left her with something less than nothing. It's an evident confection, generous with provincial whimsy - and turns out to be very merry fun. What's different? In the first place, breadth of constituency: its populist inclusiveness encompasses diverse characters and audiences. After all, no one's going to set out specifically to ingratiate middle-aged housewives with a drug peddling romp, nor dope freaks with a story of a Cornish widow's belated liberation; compounding the two, however, results in refreshingly poignant silliness. The sensibility's very Ealing, which makes it a rose-tinted vision of England, but eminently lively and charming.
