I love this film. It's one of those I can watch again and again. It is acted well by a good cast that doesn't try too hard to be star studded.
The premise of a newly widowed housewife who turns to selling pot to make ends meet could have been made into an Americanised turd of a movie or an action thriller. Either would have killed the film completely.
The film plays out like an Ealing Comedy with a terrific feel-good factor throughout.
It is worth watching just for the scene with the two old ladies and a box of cornflakes... (no that's not a spoiler!)
