The difficulty with that approach is that it's ad-hoc. For each 
situation you have to include special terms to get from the Newtonian 
prediction to the observed reality. You don't end up with one theory, 
but with as many theories as you have scenarios.

By contrast, general relativity is a single theory that addresses both 
the orbit of Mercury, the behaviour of clocks in orbit, the bending of 
light in a gravitational field, and indeed every other situation it's 
been tested against.
