According to Trekweb, LeVar Burton went to the producers and told them he was "ashamed" that he had directed this episode. See more »


When Trip tries to persuade T'Pol to come back to Enterprise with him, she refuses, saying she'd rather stay with Archer and Hoshi, but T'Pol is completely out of contact with Enterprise while she follows her two crewmates. Why doesn't she take a communicator and phaser from Trip so that she's at least able to communicate with Enterprise and defend herself? See more »


Captain Jonathan Archer: [about the mutagenic virus] This was created... as a final effort to preserve a civilization - a people. That species we became - they cease to exist the moment this virus is gone.
Dr. Phlox: Captain...
Captain Jonathan Archer: We came out here to stop the Xindi from destroying Humanity. I'll be damned if I'm gonna have a hand in destroying another race in the process.

They did this sort of thing on "Star Trek: Voyager"
29 March 2015 | by MartinHaferSee all my reviews

On "Star Trek: Voyager" there was an episode in which two of the crew members devolve into amphibian creatures (Janeway and Chakotay, I think). Here in "Extinction", the same idea is recycled--which is a shame as the previous several episodes were marked improvements in the series.

T'Pol, Hoshi, Archer and Reed land on some crappy planet. Just about immediately, they start changing into primordial creatures. With T'Pol the changes aren't as obvious. But with the other three they look and act and look a lot like characters from "The Flintstones"--all animal-like and creepy. This calls for the cast to act (or, shall I say over-act) like odd sorts of thingies. As for me, I grew tired of all this nonsense very quickly and I had to fight the urge to just go on to the next episode.

Soon after they are infected, some aliens arrive and announce that the planet is quarantined and Enterprise won't be allowed to take the infected crew members out of orbit. It DOES make sense, as apparently the virus on the planet turns folks into members of a long deceased and goofy species that inhabited the place and built cities.

So is it any good? Well, apart from being a retread of sorts AND featuring some goofy acting, the story idea isn't terrible. Hardly a glowing endorsement, I know.

By the way, SOME of the graphics for the city (particularly the one the infected folks picture in their mind) are really poor. I know it was filmed a while back when CGI was much less refined, but this was ridiculously bad even for then.
