well, however ridiculous star trek theories are, the series is based on scientific theory. with an exception to the original series, which mixed laughable action sequences along with science to solve the problems of that episode, most problems in the star trek universe are solved with science...as ridiculous as that science is.
when an alien threatens the lives of the crew of the enterprise or voyager, there is rarely a phaser fight, or even so much as a war of words. there is some scientific solution which they come up with and that is what saves the day.
in star wars, the problems are solved through action. granted, there are lightsabers, but they are not explained, they are not modified, or altered to suit a particular problem...they are just swords, swords for knights. the jedi are not explorers who discover new worlds, they are heros who fight to save the day. when you take away the technology and pseudo science from star wars, you can still have a story. its just another tale of heros and monsters and love and drama.
when you take the technology away from star trek...what do you have left?
