Warp speed: especially on Enterprise… apparently Klingon space is a hop, skip, and a jump away from Earth now.
AND: apparently exceeding the ultimate speed limit of the universe (Warp 10 post-TOS) turns you into a giant lizard (Voyager’s Threshold).
Turbolift speed: totally dependent on how long the conversation is taking (admittedly, if it’s a really long conversation, they’ll hit the stop button… but not often enough)
But the thing that really bugs me is the need to put a token hot female character in a tight spandex outfit (Troi, 7 of 9, and now T’Pol)… it’s completely gratuitous, but worst of all, when they do get to wear normal uniforms… they look much more attractive.
In TOS, the parallel Earth episodes - SciFi is running a Star Trek marathon today, and the Yangs/Coms ep was on. Barf. And why would Kirk, McCoy, and espeically Spock stand when the Yang (US) flag entered the room?
And yes, most time travel episodes completely ignore, or only pay lip service, to all the problems involved. Although, also on the SciFi marathon today, was the episode where they go back to the late 1960s and are spotted as a UFO. Kinda fun. Just ignore the beaming the 1960-ling back into their own body so they don’t know what happened ending.
Regarding sexuality - wasn’t there a TNG where Riker had gender issues with a “beautiful” alien?
I think that was an episode where he had the hots for an alien, and (s)he turned out to be from an androgynous race. I’m not sure off the top of my head, but I’ll look it up.
I found this link on a message board that talks about the episode.
That was “The Outcast”. The members of the race were gender-neutral, but Riker’s attraction to one caused it to take on female traits. Ultimately, she had to be “reprogrammed”.
Here’s another great link that discusses the plot in much more detail, and is actually rather critical of the episode.
The reviewer thought that it was a great topic to tackle in an episode (homosexuality), but that the Star Trek writers didn’t do enough to show that the Federation is a very tolerant place. Specifically in one part of the episode:
