It’s exciting to see Shyamalan on such confident footing once more, all these years later.
One of the curious problems with "Something Borrowed" is that Kate Hudson's performance is too effective. She plays Darcy, the lifelong best friend of the heroine, Rachel (Ginnifer Goodwin). Blond, rich and headstrong, she always gets her way in their relationship. As the film opens, Darcy is about to be married to Dex (Colin Egglesfield), who Rachel has had a crush on since law school. No good can come of this.
The plot mechanics are more or less inevitable. Thrown together again as the ceremony approaches, Rachel and Dex realize they have always been in love. But what to do? Rachel doesn't want to hurt her best friend. And Dex has a mother who struggles with depression; only the marriage seems capable of cheering her up.
To be married as an aid to someone else's mental health calls, I think, your own into question. This is especially true because the depressed mother (Jill Eikenberry) doesn't have a single line in the movie, and is seen only looking sad sometimes and happy sometimes. I believe, but cannot be sure, that a surprise decision made late in the film is triggered by her single ambivalent expression.
Now to Kate Hudson. She plays an alcoholic. This is as clear as day, although I'll bet you won't see her described that way in many other reviews. Among the danger signals of alcoholism must certainly be playing badminton on the beach with a glass of wine in your hand, sitting down in a bar and ordering six shots of tequila, and drinking in every scene where she is not literally being fitted for a wedding dress. If you are marrying an alcoholic and are not one yourself, you shouldn't do it to cheer up your mom.
