Director Johnny Martin did okay with 2020’s “Alone,” which was a pandemic horror movie actually released during the early months of a pandemic. Timing was a bit eerie, but Martin managed to sell a small-scale understanding of a zombie apocalypse with some skill. He’s back with “Off the Grid,” which shares the same budgetary restrictions as “Alone,” only this time out the production tries to create a “First Blood”-style display of rural intimidation and survivalist violence. The screenplay by Jim Agnew (“Kill Em All 2,” “Rage”) doesn’t color outside the lines, setting up a basic confrontation between a man in the wild and the corporate stooges coming to get it. Perhaps more twists and turns would’ve been welcome, as “Off the Grid” visibly struggles to get any suspense going, watching Martin oversee a lifeless, poorly edited endeavor that also serves as something of an overacting competition.
