...and handling the paradoxes with a family photo while keeping the duplicate characters from making direct contact.I loved the movie, but I do understand all the confusion and sentiments regarding the plot. Time travel tends to have that effect on the mind unless it is left simple, like having a DeLorean with a flux capacitor.
Up next - the whiny Skynet kid travels back, forth, and sideways in time, but Arnie will-not-stop and the world is saved yet again. Good explosions, good helicopter action. The more you try to 'explain' time-travel epics, the more confusing they get.
