This is an issue I feel rather strongly about. Good stories in any genre are about people. CSI, for example, uses more jargon than your average show ("Get the vic's DNA from these epithelials and run it through CODIS") but the writers always show us how the information gained via dry forensic procedure is affecting the characters in a vital and human way. The show is about the people, not the crimesolving technique. Most of the time, Voyager failed in that area. How many episodes were there where the solution to the problem of the week basically boiled down to the characters sitting at a console pressing buttons while spouting incomprehensible (to 99.9% of the population) made-up technobabble? That's bad writing. Period.
In the original Star Trek writer's guide, Gene Roddenberry said that a good Star Trek story should, if stripped of its science fiction elements, be able to be adapted to any other one-hour drama in primetime. How many Voyager stories fit that criteria? How many of them are really about the characters being affected in a real, organic, human way by the events of the episode?
To pick an example at random, take the episode "The Omega Directive". The whole thing is an exercise in technobabble. The only piece of character drama, Seven's reverence for the Omega molecule, is just too damn hard for the average person to relate to. Why should we care about a mostly emotionless cyborg's vaguely religious feelings for a technobabbly subatomic particle that's just a shiny special effect anyway? We're never really given a reason. Seven's dilemma is never made relatable in a human way. Most of Voyager was exactly the same. If you strip the science fiction (or science fantasy, if you prefer) elements from 98% of Voyager's episodes, you're left with nothing more than the plot for a Saturday-morning cartoon at the very most.
I realize my views are in the minority in this forum, but 99% of the viewing public didn't watch the show and were only vaguely aware of it, so I'd say my views are fairly typical in a larger context.
