Newton's LAWS of Motion are not a THEORY. They are a descriptive generalization about how gravitation behaves under stated circumstances. Those circumstances being slow speeds and large masses. In those circumstances, they are not wrong. They are a generalization. The THEORY of General Relativity contains Newton's LAWS of motion as a part of the overall framework.
