Lack of good storyline.

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

The movie runs out of plot and jokes well before the end of a two-hour running time, long for a light comedy.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.
