Completely and utterly unspoilery comments on Torchwood

In regards to that bit in the opening titles where they say the "arming the Human Race against the future", am I the only person who takes that sentence way, way too literally, and wonders why it is the human race needs to attack the future? I mean, what's the future ever done to us?

...And now I am visualising some future peoples going, "Say, look at the past, it's another country you know, LET'S GO DECLARE WAR ON IT!!!"

See, that's what I call a Time War. When your own future tries to kill you.

_{Thoughts on ep 5: Quite decent, actually. Probably the best yet. But again, still flawed, and it's the same thing still bugging me. Next week looks interestingly horrific, though}
