Movies That Are One Step Away From Sci-fi

I love when a film has a magical premise that it can get the audience to accept without ever offering an explanation as to why it happened. Any favorites?
  1. Midnight in Paris
    I really liked this movie (I know @Bourdain disagrees). It only occurred to me afterwards that there was no scene with a Doc Brown type explaining the bizarre scientific wrinkle that led to this time travel, nor was it necessary.
  2. Groundhog Day
    We are never asked to wonder why this situation has occurred scientifically: we only are asked to wonder cosmically, and what he should do about it.
  3. Beasts of the Southern Wild

  4. Cats & Dogs

  5. Matilda! All the focus is on the Trunch, and Miss Honey, and Matilda's crappy parents--WHAT ABOUT HER TELEKINESIS? Roald just throws that in there without a word. The guy had balls and it paid off again and again.
