Critical effects at complete and critical wetting in three dimensions are studied using a coupled effective Hamiltonian . The model is constructed via a novel variational principle which ensures that the choice of collective coordinate near the wall is optimal. We highlight the importance of a new wetting parameter which has a strong influence on critical properties and allows the status of long-standing Monte Carlo simulation controversies to be re-examined.
