On what basis do you say that? Although I did not set the star ratings I do tend to agree with them.
The Buick is on screen for eight minutes compared to the highway patrol car is in constant use for 1 hour 20 minutes? The main point of the movie is the highway patrolman being taken hostage and forced to drive to Sugarland with everyone in pursuit.
I absolutely agree with Sunbar: I think that it deserves 5 stars, because the movie is pratically set in it for nearly all the running time. It was used for all the movie, and most of the dramatic scenes were ambiented into this car.
