The film earns a score of 75 out of 100. After Kyle Reese travels to 1984 with the mission of protecting Sarah Connor, he discovers that things aren't as expected—the timelines have shifted and he’s experiencing memories of events that didn't happen for him. This movie often receives criticism for being difficult to understand, but I don’t see it as a significant problem; it involves time travel, and those stories rarely hold up under scrutiny. What this one does offer is impressive action sequences, an intricate narrative (which becomes clear if you focus), and a sensible ending. There's also a good amount of humor present, particularly in the back-and-forth between Kyle and the Terminator. It’s genuinely entertaining. -- DrNostromo.com
