Cool. I've always liked 70's culture. The cars, clothes, designs in general. It sort of defined the last 40-50 years.
And yeah, Star Trek is a premium sci-fi franchise. They really try to explain how things work so that you don't really suspend disbelief, you accept that "in the future" it will be solved.
Plus the types of actors they chose and the evolution of morality they were presenting, it was just different from everything else. :{
