All the ingredients for a fabulous movie are here: some interesting actors, some snappy dialogue, some stunning "fashion cameos," and some jokes at which only an insider could wince. Unfortunately, this movie is a fallen souffle. Is it a romantic comedy? Is it a series of over-the-top satiric vignettes? Is it a whodunit? Is it sincere? Is it blatantly corny? Yes, yes, yes. It never takes a consistent tone.
