YMMV / Star Trek: Voyager S3E8 "Future's End"

• Complete Monster: Henry Starling was a hippie camping out in the mountains of California in 1967 when he discovers a crashed time ship from the 29th century. Starling takes tech from the ship, developing several computer products from it—creating the computer revolution of the 90s—forming a company called Chronowerx and becoming a powerful tech mogul. In 1996, Starling plans to use the time ship to go to the 29th century and steal more tech to make into products. This will cause a massive explosion that will wipe out Earth's solar system in that time. The Voyager crew arrives in 1996 to stop him, but Starling steals the Doctor's program and changes his program to torture him for information. Starling also rigs the time ship to explode if Voyager tries to beam it away, which would destroy Los Angeles. When Captain Janeway tells Starling his trip to the future will destroy the Earth in the 29th century, Starling does not care, willing to risk billions of lives for sake of his greed.
• Ensemble Dark Horse: Rain was a fairly popular element of this episode due to some funny interactions with Tuvok and Paris and the amusement value of a modern-day SETI member capturing a Starfleet ship in the sky. Being played by Sarah Silverman right before she became more famous also helped, but reportedly the production liked her enough there was actually some talk to bring her into the main cast. As is, she remained a two-episode (one-story) character.
• Growing the Beard: This two-parter is often considered to be where the show really started to come into its own. In addition to being a strong story in its own right, it marked a major change in the status quo by giving the Doctor his mobile emitter, thus allowing an already-popular character to take a much larger part.
• Harsher in Hindsight:
  • Captain Janeway's "The Reason You Suck" Speech.
    "In my time, Mister Starling, no human being would dream of endangering the future to gain advantage in the present."
  • When Rain catches Paris out on the fact the Soviet Union collapsed and the KGB is defunct. Fast forward to The New '10s, with the rise to power of ex-KGB strongman Vladimir Putin and accusations of using KGB-style tactics to silence his opponents and critics, and cooling relations between the United States and Russia (in particular over the annexation of Crimea, and investigations into Russian agents directly subverting or attempting to subvert the 2016 Presidential Election in favor of Donald Trump).
• Hilarious in Hindsight:
  • Starling demands Captain Janeway's psychological profile from the Doctor. The Doctor promptly diagnoses Starling with bipolar personality disorder, a popular fan explanation for Janeway's Depending on the Writer portrayal in later seasons.
  • Captain Braxton's defining line, "A leads to B, and B leads to C...." is hilariously cringe-worthy in a post-Human Centipede world. Especially since Braxton is (kind of) a Mad Scientist.
  • Hadassah Gouberman on call for alien communication, ready to represent Earth to the universe over the phone.
• Narm: Any scene where Starling is typing, as Ed Begley Jr.'s hands clearly never leave the home keys.
• Retroactive Recognition: This episode features a young Sarah Silverman at the very beginning of her career. She had only appeared as a bit player in Saturday Night Live and Mr. Show by this point.
