Chronicles of Riddick, a piss poor attempt at either Lord of the Rings for Sci-fi fans or dune lite, so far up it's own rear end it was a bit difficult to fathom what the hell it was about.
Yes. You are correct. Clerks II was so disappointing compared with the first one, but then again, the first one was one of the greatest films of all time.
The paradox of the Terminator saga is that John Connor and his mother attempt to prevent the future apocalypse.
By depicting these events T3 sets them in stone thereby negating the entire point of Cameron's films that the future is not essentially pre-determined.
From what I can gather T4 wisely side steps this gaffe & is set before John Connor senRAB Reese back so T3 can be retconned out of existence.
Actually it doesn't negate anything. It means that Sarah/John tried and failed, it doesn't mean that they couldn't have stopped it if they had done something different.
