How do the different casts affect the plots in Star Trek?
Star Trek has gone from a real cowboy approach to handling things. Captain Kirk was a very physical guy, he�d grab the phaser, take care of problems, and hold up the big stick and threaten people. It�s gradually changed over the years, with Picard negotiating quite a bit more and calling conferences. Then on Voyager there�s very much a sense that hi-tech is our solution. They�re appealing to the Silicon Valley types.
You have script after script of Voyager where they�re in a grave situation and all they have to do is modify something or modulate something and they can get out of a situation. That started a little bit on Next Generation, where they had a situation in one of the scripts midway through where alien probes had infested the computer core of The Enterprise. It was damaging the ship and there was a chance the ship could explode because of it.
After trial and tribulation, they realised that, amazingly enough, all they had to do was re-boot. They shut down The Enterprise and then, two minutes later, they started it up again. If that isn�t catering to the hi-tech Silicon Valley-type crowd, I don�t know what is.
