I will present a new approach to study the RG flow in 3d N=4 gauge theories, based on an analysis of the
Coulomb branch of vacua, focusing on U(N) SQCD theories with fundamental matter. The Coulomb branch is
described as a complex algebraic variety and important informations about the strongly coupled fixed points of
the theory can be extracted from the study of its singularities. I will use this framework to revisit and clarify the
classification of infrared fixed points in U(N) SQCD with different amounts of matter hypermultiplets, in
particular for the so called ``bad" theories.
