The Terminator is the only film that uses time travel as a plot device that I respect. This is because there is no paradox: although Skynet tries to change the past, it inadvertently causes exactly the future it was so desperate to escape. This raises all sorts of horrible questions about free will, so I hope it’s not how the actual universe functions, but as a narrative structure I find it satisfying, even poetic, that all the time travel shenanigans simply create a self-sustaining loop.
All the other films throw that out the window. Chris and I argue they should not.
