The real value in Mope is stripping the sheen and the glamour off of porn, still shot, as it was in the pre-Internet “Boogie Nights,” in the unfashionable San Fernando Valley (Van Nuys and environs).
The problem with gruesome true stores is that, if the outcome is known, a film needs to work well enough for you to patiently wait for it to get to the climactic re-enactment of the crime. Mope does not garner enough interest in either a storytelling or visual regard.
