  We consider two-dimensional metals of fermions coupled to quantum critical
scalars, the latter representing order parameters or emergent gauge fields. We
show that at low temperatures ($T$), such metals generically exhibit strange
metal behavior with a $T$-linear resistivity arising from spatially random
fluctuations in the fermion-scalar Yukawa couplings about a non-zero spatial
average. We also find a $T\ln (1/T)$ specific heat, and a rationale for the
Planckian bound on the transport scattering time. These results are obtained in
the large $N$ expansion of an ensemble of critical metals.
