"Emma Woodhouse, handsome, clever, and rich, with a comfortable home and happy disposition, seemed to unite some of the best blessings of existence; and had lived nearly twenty-one years in the world with very little to distress or vex her."
That's probably the best ever description of Emma's caracter. The plot is about a young woman who is very busy with other's marriage business, even to the point of not perceiving her own feelings.
Though some critics have claimed lack of story, dozens of adaptations for television, cinema and theatre seem to indicate otherwise. The minutiae about trivial matters of daily life does not compromise the plot's appeal.
