- Awesome Music: The short theme song, "Mighty Little Man" by Steve Burns.
- Author's Saving Throw:
- The episode that reveals how Sheldon adopted "Bazinga" as his catchphrase also makes it clear that his habit of saying it after pulling not-all-that-funny jokes was itself not all that funny.
- You can tell just by watching the show that the creators have gone out of their way to not repeat the things that many have criticized The Big Bang Theory for. For instance, the show is presented as a single-camera, laugh track-less dramedy shot on-location as opposed to the outdated, but still widely used three-camera sitcom shot on a sound stage in front of a studio audience. The characters on Young Sheldon are likable and sympathetic despite their flaws, as opposed to the Unsympathetic Comedy Protagonists on Big Bang. (i.e. Sheldon having more redeeming qualities, Mary being less aggressive with her religious beliefs, George Sr. being a normal husband and father instead of the drunken, idiotic, misogynist described posthumously in Big Bang).
- Base-Breaking Character: Missy. Some people think that she's hilarious, adorably mischievous and a brilliant contrast to the calmer and more composed Sheldon, with a more vulnerable side that explains her bratty attitude at times. Others think of her as nothing more than a spoiled brat, who is constantly rude to her family, and who only ever thinks of herself. However, both sides often agree that Missy's actress is one of the best in the show, despite her young age.
- Fandom Rivalry: While it does have a better reception than its parent show, it still has a bit of a rivalry with The Goldbergs with fans of the latter accusing the show of being a rip-off to cash in on the show and The Big Bang Theory ending.
- "Funny Aneurysm" Moment: In Episode 7, after she sends him all the way to New Orleans on a fools' errand, Sheldon's father says that Mee-Maw can come to the house when he's not home or when he's dead. Given that we know Mee-Maw will still be alive by the time Sheldon is an adult but George Sr. will die in the next five years, the joke takes the scene from funny to somber for the audience.
- Harsher in Hindsight: George Sr. has a heart attack in Episode 3. He dies approximately five years after the episode takes place.
- Jerkass Woobie:
- Mr. Gilford in "A Math Emergency", due to his half-assed philosophy of Screw Politeness, I'm a Senior!. As he puts it, "I'm old, I'm alone, I'm gonna die soon!"
- Missy Cooper acts out and talks back to her parents, but its also clear she's only doing this because she feels like The Un-Favourite.
- Sheldon himself can be this at times.
- Paige, in the episode "Body Glitter and a Mall Safety Kit". Her parents have gotten divorced and she starts acting out because she blames herself and can't handle the sudden changes. Even though she framed him for shoplifting (thankfully, no one was caught), Sheldon can't help but try to comfort her.
- Older Than They Think: This isnt the first time that Zoe Perry (Laurie Metcalfs daughter) is playing the younger version of Metcalfs character, as Perry played a younger Jackie, whom Metcalf portrayed in Roseanne.
- Signature Scene: The Season 2 finale, which shows The rest of the Big Bang Gang as kids, is considered to be the highlight of the series, as a glimmer of optimism in an otherwise depressing episode. It helps that this episode aired immediately after its parent show's Grand Finale.
- Surprisingly Improved Prequel: Reception for Young Sheldon is miles more positive than its parent show. Due to the differences in formatting and jokes (dramedy angle, plots based on family, single-camera Mockumentary style), it's seen as more accessible to viewers that either have never heard of Big Bang (thus making it easier to get into) or don't care for it and its comedy style.
- The Woobie:
- Dr. Sturgis. He's a social outcast, widely disliked by everyone other than Sheldon and Meemaw. Even the other Coopers are indifferent towards him. George tries to befriend him at Mary's behest, but it's clear that he only does so out of pity and obligation to his wife. He's also suffering from mental problems, breaking up with Meemaw because he doesn't want to burden her, even though they both deeply care about each other. And he's mistreated by her new boyfriend Coach Ballard. It's hard to see such a nice man go through all that undeserved crap.
- Georgie after Dale's store is robbed. He is racked with guilt over the incident and uses his own money to cover the amount that was stolen. Then he gets fired after Dale takes the money. Fortunately, this is reverted in the Season 4 premiere.
- Tam, Sheldon's best friend. His family was forced out of Vietnam and into the States after his father fought on "The Wrong Side", and his family's first attempt at a new life is dashed by racists. In Medford, it is implied that he has no friends besides Sheldon, and his home life is strict. Things get better for him though...
- Billy Sparks of all people is shaping up to be this in Season 4. The Big Bang Theory set him up as a bully who enjoyed making Sheldon's life miserable. By contrast, this show portrays him as a dim, but friendly CloudCuckooLander. He has no friends and his father left him alone with his mother, who seems embarrassed by him. Even Sheldon, who used to hang around with him in prior seasons, pretty much ignores him.
YMMV / Young Sheldon
