As a prequel to the Trek franchise, Enterprise was jam-packed with continuity porn. Some of it was so subtle I missed it until I read about it online (alien races met in the first season were namedropped but never seen in TOS, such as the Axanar), others attacked the viewer with the subtlety of a sledgehammer wrapped in barbed wire ("Maybe.... artificial life forms. It may take a few... Generations"). Which are your favourites? -Arik Soong's "I call it the 'Briar Patch'" -Zefram Cochrane originating the "Captain's credo" in "Broken Bow" -Andorian ships having the TOS-style double front console and Vulcan ships having classic movie-style console graphics. -The Augment arc, an excellent Khan prequel (and with unintentional yet awesome foreshadowings to the latest movie, such as the mention of Archer's father, and effortless Klingon whuppings) -The Klingon forehead thing. Totally unnecessary, but totally awesome. When the female says she felt fear for the first time since she was a child, it also explains why TOS Klingons acted so much like villainous humans and so unlike the movie/TNG/etc versions.
