While all three previous films in this time-traveling sci-fi franchise gave us glimpses into the devastated futureworld run by the self-aware computer Skynet, Salvation is the first entry to be set entirely in that future, which sets it apart and gives the franchise a new look, but also weighs it down with so much grit and gloom that there’s no fun left. For all their philosophical conundrums about technology, love, and fatalism, the Terminator films have always been fueled by B-movie bliss writ (increasingly) large, which despite all the admittedly impressive firepower on display, this one is studiously lacking.
