Weakly disordered superconducting films can be driven into an anomalous low temperature resistive state upon applying a magnetic field. Recent experiments on weakly disordered amorphous InO$_x$ have established that both the Hall resistivity and the frequency of a cyclotron-like resonance in the anomalous metal are highly suppressed. We show that both of these observations con be understood from the flux flow dynamics of vortices in a superconductor, without requiring an emergent particle-hole symmetry. Results for transport are obtained using a systematic hydrodynamic expansion, controlled by the diluteness of mobile vortices at low temperatures.
