4. The Terminator
Contrary to popular belief, the original Terminator left things tied incredibly tight; its a time loop of John Connor sending Kyle Reese back in time so he can be his father. It was only with the more loved and less dated Judgment Day that things got messy. The film introduced the titular date when Skynet would become self aware and overreact a little, but swiftly did away with it, replacing the originals destiny message with a more confusing make your own future slant. Still, it felt like natural progression. The real problem was once Cameron left the series. Rise Of The Machines really just altered what had been in the previous sequel, but with less imagination. Just as the T-X was an illogical T-1000 (with the notable addition of boobs), the time travel this time around was a mixture of that proposed in the first two; you can make your own future, but only skirt a little away from your eventual destiny. Hard to swallow, but we just about went with it. Then Terminator Salvation messed it up further, bringing us a more advanced future than predicted, purely so Arnie could cameo for three seconds. Its to be expected from a time travel franchise to be hard to follow chronologically, but the release order for Terminator is impossible to fully grasp. We start at the end of the war, only to return to the beginning, then stop in the middle of similar, but all over different one. And we doubt the now confirmed fifth film will do anything to help.
