I never really thought about how screwed the Ewoks were.  Or for that matter, the Na’avi.  Though I don’t really care about that, because Avatar was awful.  Terminator, though, I always figured they didn’t send a ton of robots back in time due to some idea that maybe that might rip the fabric of spacetime and destroy all life as we know it.  Maybe not.  I like those movies.
