Despite a terrible name and a steady decline in cinematic franchise quality, the new Terminator: Genisys trailer doesn't suck. In fact, it's far, far better than I had any right to expect, in large part because it's continuing the theme of temporal riffing that began in The Sarah Conor Chronicles.
We are trapped on Earth. It's something I felt keenly as a kid, which is why the destruction of Challenger, and then Columbia, hit me so hard. Hell, I still tear up just thinking about January 28, 1986, but neither tragedy changed my mind about the importance of space exploration and colonization.
