The direction of the homage (and it is homage, not plagiarism) is the direction
everyone says it is, no matter which text came first. Yes, Days of Future Past
came first, but Terminator and Terminator 2 don't actually share that much
in common. Bryan Singer borrowed exactly the right amount from one of the
greatest action films ever made to make what is in my mind a contender for that
same title. Days of Future Past does what a good homage to another work does: it
enriches it. Terminator 2 is just about war, but Days of Future Past tells us
that the causes of war matter too, and that we have to not just learn to get
along generally but also learn to tolerate each other the way we are. Days of
Future Past thus ties in gay rights, racial relations, and other issues into a
story about the importance of peace.
Thanks, Jeff, I never before made the plagerism connection between the Outer
Limits episode "The Soldier" and "The Terminator". Now had I
seen Arnold talking to a cat(Control?) in the 1984 Movie version, that would
have been a tip off. I'll have to see "Demon with the Glass Hand"
episode again tonight. There, I remember the Character is being chased
throughout the episode by a hit team from the Future. But his name wasn't
John Connor as I recall either.
