YMMV / Splash

  • Ensemble Darkhorse: Dr. Kornbluth, the Large Ham Ineffectual Sympathetic Villain, easily steals every scene he's in.
  • Hilarious in Hindsight: See Line-of-Sight Name on the main page. Madison is now one of the most common female names in the United States.
    • A scientist trying to prove supernatural creatures exists. Sound familiar?note 
    • The boat Tom Hanks is riding in randomly loses power halfway between the mainland and an island. The pilot generously attributes the problem to him intentionally rocking the boat, but that's because this was decades before the world learned never to travel with Tom Hanks.
  • Moral Event Horizon: Dr. Kornbluth calls out the other scientists, particularly the leader Dr. Ross, for planning to dissect her. But they merely insult him for "not being a real scientist," expressing how Kornbluth would always be a disgrace in his eyes and the eyes of the scientific community no matter if he is considered crazy or not. This helps lead to his Heel–Face Turn afterwards, and also makes Ross look like an idiot since he could have gotten into the history books as the one who established contact with a new race if he wasn't such a "sadistic pig".
  • MST3K Mantra: Don't try to figure out how Madison is able to read a map despite having had no previous contact with the English language.
  • One-Scene Wonder: Kornbluth's mentor
  • Romantic Plot Tumor: Inverted. The basic story is a romantic comedy, but once Madison's secret is exposed, it turns into escaping the government scientists who want to capture her and "research" her.
