Star Trek is space opera like the horse operas it was patterned after. But it was so surreal, it could have been anything that supported a good story. Even Kirk said it all seemed like an elaborate hoax. Anew Star Trek should be as different as possible to attract a whole new audience. The trappings of TOS has seen it's day. The Next generation was successful even though it wasn't wholly inspired and perhaps shouldn't have been as successful as it was. Only time will tell. Since now Star Trek is in competition with itself. It has to be as different from TOS as possible.
I agree and disagree to a certain point. I think that TOS presents a facet of Trek that was good for it's day but also has many of the more timeless elements of Star Trek in it. Cooperation, adventure, social commentary, etc. with characters who are actively seeking a solution to the problem of the week.
Star Trek, as I have mentioned before, really thrives with characters who the audience can identify with and with questions that reflect society's current questions. TOS did this well, but as time moves on, the questions have changed.
So, I think a new series would do well to remember the core of Trek as well as be willing to adopt a more contemporary view on technology. Remembering that the tech is not the most important part of the story, and should only be front and center when necessary.
