Short stories are much harder to get right because you have so much less time to develop characters and plot and set up the scene. This is why I usually avoid them because I invariably end up cringing or shrugging with indifference. There are a few writers, however, that I know will not disappoint. Atwood is certainly one of them. 

The stories in this collection are longer in format and I would classify them as literary. I especially liked "True Trash" and "Hairball". These are not "easy" stories to read and most of them have a dark or tragic bent. However, the quality of the writing is such that it makes reading them a pleasure even if you're left feeling sad.

If you need a masterclass in the short form, I highly recommend any of Atwood's short story collections.
