Movies using faster than light travel, will often talk about charting a course. They are referring the need to go around the stars and stuff and not through them.
The thing is, there is very very very little stuff out there. As big as some stars can be, and that's very big, the size of the universe is so much bigger, that if you point a ship directly at a star the size of our whole solar system, by the time you got to that huge star, you would miss it. You must correct for the tiniest navigational errors and incalculable variations is gravitational forces.
Also, even at warp 10, it would take you 6 months to get to Alpha Centauri, our nearest neighbor.
