Actually, I would argue that Terminator is entirely based on a Grandfather paradox: the mission of the Terminator was to eliminate someone so annoying that they would send someone into the past (a huge effort) to target them, when success in the mission would imply the negation of the need for the mission, thus making the mission not happen so that Connor would, in fact become a problem.... it's still the same paradox.
You can add on the implausibility that a person could follow you back to stop you, since presumably any changes you make in the past happen, effectively, instantaneously in the present. (TimeCop got that right)
