Drama is over-the-top ridiculous. The goal of the plot seems to be to throw as much sex, rain, and suggestive conversation, together over forced coincidences and a "trust no one, everyone is evil" message.
Renée Zellweger seems to be trying to get the most mileage she can out of her new look, and is very full of herself with this cartoonishly evil character. It's her last hurrah, I suspect. A shame really, because I don't think she needs to try so hard.
Unbearable to watch.
