Adaptation Displacement: Chances are, if you mention this movie to someone, they're going to think of the Eddie Murphy one without realizing that the first version was in the 1960s.
Critical Dissonance: The film has received positive reviews from critics, yet its audience reception is less than favorable, sitting at 44% on Rotten Tomatoes.
Ensemble Dark Horse: Reggie Warrington counts for a lot of reasons, also that Dave Chappelle played him. He was SO popular that Chappelle reprised Reggie in one of Chris Rock's albums.
Friendly Fandoms: Interestingly, fans of the original and of the remake get along very well, agreeing that both have their pros and cons. It helps that both films take their own distinct approaches to the comedy, fitting their respective stars' styles, meaning neither comes off as trying to outdo the other.
At the beginning of the film, Dean Richmond mimes shooting Klump out of annoyance of his repeated goof ups. While at the time it was considered hilarious due to how unrealistic it seemed that fellow administrators/professors would end up using firearms, the comment is now considerably less funny after the University of Alabama at Huntsville shooting where a professor shot and killed three coworkers and wounded three other employees due to being denied tenure.
Buddy derailing Reggie's set became this in May 2022 when Dave Chappelle was attacked by an audience member. Unlike Buddy, the man was beaten up by security.
The Humor Dissonance scene where Buddy Love heckles and then beats up the hack comedian played by Dave Chappelle plays differently in 2021, when Eddie Murphy had apologized for punching down early in his career as a comedian while Chappelle has courted controversy for repeatedly mocking Transgender people in his stand-up specials.
Nightmare Fuel: Buddy putting Reggie in his place may be Laser-Guided Karma but it's also fairly disturbing. One particularly disturbing moment is when Buddy appears to break Reggie's wrist at the piano and the latter wails and cries in pain. There's even a Sickening "Crunch!" sound to boot.
While the prosthetics from both films remain impressive, most of the computer morphing effects used to show the morphs between Buddy and Sherman have aged very poorly, especially the ones from the first film's climax.
There are several instances in the Klump dinner scenes where Sherman and Ernie's arms pass through each other.
During his meeting with Dean Richmond, Klump sees a hamster on the chandelier pooping and its droppings land in Richmond's coffee, which the oblivious Richmond ends up drinking down, despite Klump's attempts to warn him. He then gags and then the hamster falls into the coffee, splattering him.
"You know Mike Douglas used to make me moist when I'd watch his show?". Cletus Klump gets an understandably cringe-inducing reaction at hearing Grandma fantasizing with hooking up with men her age (not to mention being accompanied by the oh-so-pleasant mental image of an elderly wet vagina) and proclaims that he wants to take the old bird out of her misery. (Though, Mike Douglas was most famous during The '70s, 20 years before the events of the film.)
The Woobie: Professor Klump. Comedic as the remake is, it does also show how his obese situation is affecting his life negatively. His Amazingly Embarrassing Parents don't help, either.
