@ Dave: I think you may have slightly missed the point .. Murray's character doesn't simply "Hop into bed with his co-worker" as you say, but rather he develops a more sincere appreciation (some would say a "loving" one) of her because of his own personality development through the film and the inference is that once he finally moves forward from the day that the 2 characters will engage in a loving relationship. I think it might be you that's a little shallow if that's the only conclusion you drew from the film!
