What are the successes and failures of the Lewis theory in explaining chemical bonding?

(N/A) The Lewis approach is successful in explaining the sharing of electrons between atoms to form covalent bonds and the formation of simple molecules.
However,it fails to explain the following:
$1$. It does not explain the shape of polyatomic molecules.
$2$. It does not provide information about the energy of the bond (bond enthalpy) or the bond length.
$3$. It fails to explain the stability of molecules based on the electronic configuration.
