STAR TREK IS: Space opera, action and adventure, playing fast and loose with real science to make it fit whatever serves the plot. Character chemistry, interaction, making the story play well onscreen. Characters are the focus. It's fun, memorable (or not), and fun. Talky, unless budget allows a good shoot em up.
STAR TREK IS NOT: The history of the future, a plan for the course of humanity through the next few hundred years, a serious study of what can be accomplished if we are only intelligent enough to pursue it.
People get way too serious about this stuff. Star Trek was very nearly dead more than once in the last 45 years. We've had more chances than a lot of fans get with their favorites.
Sit back and enjoy the ride.
