I'm having a premonition

The movie trailers for Sandra Bullock's new movie 'Premonition' looked like it would be a really good movie full of twists and turns, but the early reports from movie goers is much less opptomistic. Some say they laughed through the entire thing--it's not a comedy. Some say the ending left them feeling let down. Most seem to feel it's so unrealistic that the premonition should have been to not release it in the first place. Sad... I like Sandra Bullock.
