Oh my gosh, I cannot believe your #1 answer is that! Every single time I see a crewman flying around the bridge, I can’t help but say, “See, seat belts save lives!” I’ve got it down to a magnetic coupling which turns on when battle happens and turns off when no significant event is going on (or when a button is pushed), to allow crewmen the flexibility to do their job but to also be safe and able to attack if the bridge is taken. One big thing that irked me in Voyager was Janeway’s wishy washy upholding to the Federation guidelines and rules. I mean, she had no problem destroying the array at the beginning, but then throughout the series she wavers here and there and second guesses herself… Oh, how about sounds in space? Gotta love that one. I also hate every time the Borg is shown to be stupid, such as in the entire plot of First Contact. I was frustrated at the technical jargon and the lack of meaning any of it actually had. It sure wasn’t consistent across the entire franchise, and many times it feels like the writers simply created a solution for why the ship was malfunctioning via some simple word game: the [equipment with a suffix of -lator, -sister, -ion] is [some descriptive word, usually related to damaging] the [protons/neutrinos/particles or add anti to any of that]. I have to say I really approved of Battlestar Galactica’s realism levels (I mention BSG because of Ron Moore’s involvement), but its dialog sucked. With Star Trek I almost feel it’s the opposite, the dialog and plot was (for the most time) good but the realism was one step back from where it could have been.
