"it's still fair to say Newtonian mechanics is an "incomplete" view of the universe" The arguments back and forth on this fascinate me. On one hand, on some scales, Newtonian mechanics is "correct enough" to give results that work, and so in that sense it is just "incomplete" in that its domain is restricted. On the other, relativity and QM change everything. These new theories may reduce to Newtonian mechanics given certain assumptions, but Newtonian physics says things about the structure of spacetime that are incorrect (e.g. velocity is not additive). In this sense, one can fairly say that Newton's mechanics are not just incomplete, but wrong.
