There are alot of things I would change..... firstly would be the car.....
It is rightly said that no one can compare the two until the first season is made... but I hope that they don't do everything in the first season and run out of ideas..... TKR ahad that problem and so will this.. if they aren't two careful.
Anyways back to the topic at hand.... I cannot compare series, but I can compare pilots. The new one spent alot of time trying to get the story align with the old one and still did not manage to tie up alot of loose ends. The old one kept the story plain and simple.
The old one had alot of stunts... but this consisted more of repetitive jump after jump after jump.... It also did prove the car was an all powerful weapon that could not be stopped.
The new one tried to get that image across, but it gave us a more realistic glimpse of the current world. While one is capable of inventing a talking car... it is nevertheless a computer and today's world is no short of brilliant hackers.
I would have loved to see the Mustang do more, but hey... there is only so much you can put into a TV pilot. Now I hope get put into a series and we can really see what the Mustang can do...
