Internal Consistency Problem?

Rating: Null/10 (18 March 2002)

WARNING:POSSIBLE SPOILERS AHEAD. Very riveting. One of the holes in the plot however is the fact that when John Conners-Sarah Conners' son sends his dad back from the future to rescue his mom from Arny, he makes her pregnant with....JOHN CONNERS!! Pop had to go back in time for his son-who ordered him to go(interesting family chain of command)TO EVEN EXIST IN THE FIRST PLACE! I wonder if this should lead to a prequel. Was Sarah already in an alternate time line, already touched by time travel? No doubt, it's probably hard to do a movie or story about time travel without some internal consistency problems. For example, in movies like Back to The Future II, where Marty & Jennifer see their future selves. Seems theoretically they should have discovered that their future selves disappeared the day they went into time warp, casualties of their own time travels! All that said, use of time travel stories as metaphors of observing & experiencing variables in the impact different choices can have on our destiny can more than make up for not being scientifically correct. Especially since no body's sure if time travel itself is even possible- much less scientifically correct. Nevertheless, when I see anomalies like the aforementioned conception, I find it worth noting.
