Premonition

I saw the movie Premonition last Saturday. Here's the synopsis from the official site:

Linda Hanson (Sandra Bullock) has a beautiful house, a loving husband and two adorable daughters. Her life is perfect, until the day she recieves the devastating news that her husband Jim (Julian McMahon) has died in a car accident. When she wakes up the next morning to find him alive and well, she assumes it was all a dream, but is shaken by how vivd it felt. She soon realizes it wasn't a dream, and her world is turned upside down as the surreal circumstances lead her to discover that her perfect life may not have been all that it appeared. Desperate to save her family, Linda begins a furious race against time and fate to try and preserve everything that she and Jim have built together.

This movie was weird because the ending was not what you would expect. You know how usually in movies like this, they try to make you think the ending is going to be what you expect but then it turns out in a good way that you weren't expecting? Well this movie started out like that then it turns out that what you were expecting would happen all along actualyl did happen so it kind of made the entire movie seem pointless. Like what you thought was going to happen the entire time actually happened...it really made the whole movie seem pointless.
Now I really liked the movie itself...the actors were great and the effects and stuff were good, and even the plot was ok; the ending was the only thing that threw me off, because it was what I was expecting.
Has anyone else seen this movie? what do you guys think about it? Is that weird that the ending is exactly what the audienceis expecting?
