I'm shocked by how many excellent female Authors are around these days. I won't make any names because they are already an army and I don't want to forget someone or give the impression I'm giving rates, which is something I'm not even remotely qualified for.
Feminine point of view is overwhelmingly interesting to me.
This film is good: it's a love story. Simple plot, made on a low budget but you won't notice because it has fine particulars: the fighting in the alley, very realistic; high quality images (see how Waterloo Station fills the eyes); perfect narrative balance and a very good, really convincing acting.
It's a comedy, not a lecture about eating disorders. If you don't like the genre you won't like the film. But if you like this kind of flicks, I guess you'll be nicely entertained.
