YMMV: Sling Blade
- Big Lipped Alligator Moment: Karl's baptism.
- This is debatable as he has just made things right with his father and forgiven himself for what happened to his brother.
- Crowning Music of Awesome: All of Daniel Lanois's score. Also a well-placed country ballad when Karl and Melinda are on their 'date' and she brings him flowers.
- He Really Can Act: Billy Bob Thornton is so known for playing Jerks and Sleazes that seeing Him as the gentle but unstable Karl is something of a shock.
- Also, country singer Dwight Yoakam is surprisingly damn frightening as Doyle.
- Hollywood Homely: Billy Bob Thornton was told by Billy Wilder that he was too ugly to be an actor and should write a screenplay to exploit his features.
- I Am Not Shazam: Many people who are unfamiliar with the movie think that Sling Blade is the protagonist's name. Evidenced by closed captions that say:
[[Insert character name]] (Imitating Sling Blade): Mustard and biscuits, mm-hmm.
- Moral Event Horizon: Doyle's may be when he flings poor Terrence in his wheelchair against the screen door in the act of kicking his band out.
- Frank Childers's was carried out long before the events of the movie, as related by Karl: he expected Karl to dispose of his premature little brother as though he were trash; the follow-through to this unseen event is shown in the Heartwarming Moment above.
- One-Scene Wonder: Robert Duvall as Karl's father.
- Some folks call me Shazam: Because of the film, "Sling Blade" is used by some as a derogatory term for the mentally challenged.
- Tear Jerker: Karl relating to Frankie how his father made him dispose of his prematurely-born little brother in a trash barrel, when he was "six or eight"; even then it didn't seem right, so Karl took the tiny being and gave him a decent burial in the backyard.
- Made a bit worse by the fact Frankie delivers a What the Hell, Hero? to Karl for this; but being mentally challenged and a little boy, he had no idea how to care for any baby, let alone a premature one, so it was a bit misplaced; still, it does speak to Frankie's high moral fiber.
- The Woobie: Frankie. He is consistently oppressed by his mother's boyfriend, as well as constantly being turned down by his crush Karen Cross. He does get his share of hugs, but don't you feel like you need to give him one more?
- To say Karl had a crappy life is one heck of an understatement. He was forced to live his childhood in a shed with a dirt floor, sleeping in a hole in the ground. He was bullied constantly by all the children his own age and treated like crap by everyone including his own parents right up until he killed his mother and her lover.
