  We investigate the possibility of finding a zero-temperature metallic phase
in granular superconducting films. We are able to identify the breakdown of the
conventional treatment of these systems as dissipative Bose systems. We do not
find a metallic state at zero temperature. At finite temperatures, we find that
the system exhibit crossover behaviour which may have implications for the
analysis of experimental results. We also investigate the effect of vortex
dissipation in these systems.
