Franchise as a whole
"Dan: So Star Trek and Next Gen are about a resource rich society that is in such a creative rut they will send the Enterprise, humanity's finest ship out to unexplored corners of space just to find new life and new civilisations. Novelty is the most precious commodity there is! This is a profoundly bored people, so jaded, that they will load up their children and women onto a heavily armed warship and send it just out... just go! Just go somewhere and find me something interesting and tell me about it?!"
 * Alternate Character Interpretation: Cracked had a blast pointing out the horrifying undertones to Federation Society.


 * Contested Sequel: Star Trek XI (referred to by some fans simply as 'the Abrams film' or similar) has caused a Broken Base within Star Trek fans between people who only like the old Trek, people who only like XI, and people who like both.
 * Creator Worship: The Great Bird of the Galaxy himself. Rick Berman, Ronald Moore and J. J. Abrams are a bit lower on the hierarchy. Brannon Braga is, unfortunately, often villainized for what happened with Voyager and Enterprise.
 * Crowning Music of Awesome: Various theme songs.
 * Deconstruction Fic: All over the place.
 * Fan Dumb: Quite possibly Ye Originale Fan Dumb, at least in the sense we think of it today. Mercilessly skewered in the documentary Trekkies, which featured the juror who wore her Star Fleet uniform to court and one fan who seriously thought about getting his ears surgically altered to look Vulcan.)
 * Fountain of Memes: A Long Runner like Trek has spawned more than a few. "To boldly X where no one has Y'ed before", Resistance Is Futile, green chicks, and KHAAAAAAN! are some of the more memorable.
 * Ho Yay: Every series has at least one hugely popular slash pairing, and sometimes more than one. Slash fans will insist these characters want nothing more than to do each other, no matter how heavily contradicted by canon.
 * Kirk/Spock (or Spirk) is the original Slash pairing.
 * Spock/McCoy from The Original Series.
 * Picard/Q from The Next Generation.
 * Garak/Bashir and Bashir/O'Brien from Deep Space Nine.
 * Janeway/Seven from Voyager.
 * Archer/Reed, Tucker/Reed and Reed/Hayes from Enterprise.
 * Hilarious in Hindsight:: In the 30th anniversary special, there is a skit featuring the cast of Frasier sserving on the USS Voyager under Janeway. At one point, a Klingon beams aboard with the dog, which had been digging up azalea bushes on the Klingon homeworld. Janeway remarks, "Now you see why we shouldn't have pets on starships".
 * Mary Suetopia: Roddenberry's vision for Trek, but especially the first season of Star Trek: The Next Generation.
 * The Problem with Licensed Games: Star Trek has been notoriously variable with the quality of its forays into interactive entertainment - partially because distilling the essence of the best episodes of the series into a truly interactive format is goddamn hard. The "best" Trek games to date have been somewhat more combat-focused than many of the shows really were. Of course, the fact that the license keeps bouncing between hands and developers (unlike Lucas Arts, who've been refining their Star Wars offerings for the better part of two decades now) has not helped matters in the slightest.
 * The two genres which are widely considered to have been most adaptable are strategy games (Star Trek Bridge Commander, Star Trek Armada, et al) for the combat elements, and point and click adventures (Star Trek: 25th Anniversary (video game), Judgment Rites, A Final Unity) for their episodic nature and ability to explore some of Trek's more ponderous aspects. 25th Anniversary and A Final Unity in particular are often held up as being the closest you can get to actually playing interactive episodes of their respective television series, complete with the complete original casts providing the in-game voices of their characters (which helps a lot with the atmosphere).
 * Sequelitis: it began with the very first episode of Voyager, but by the time Insurrection rolled around, even major critics were noting that the franchise was taking a fairly serious and noticeable dip in quality. Enterprise and Nemesis are "credited" with coming within a whisper of killing the franchise (Nemesis being the only Trek film in history to not turn a profit); the reboot salvaged it, but the quality of sequels to it remain to be seen.
 * Visual Effects of Awesome: Watching a later Star Trek episode is almost like watching a movie in television show form. The best examples would likely be "The Best of Both Worlds" (TNG), "The Way of the Warrior" (DS9), "Scorpion" (VOY) and "Twilight" (ENT). Of the movies the favorites are Star Trek II the Wrath of Khan, Star Trek First Contact and Star Trek.
