* BadassDecay: The T-Birds and Pink Ladies as organizations, relative to the gangs from the first movie. The original T-Birds had no fear of the Scorpions and were prepared to rumble with them at a moment's notice, even with such inadequate weapons as a squirt gun and a switch-comb, whereas Johnny's crew are afraid to face Balmudo unless he's alone. Meanwhile, the original Pink Ladies were ''not'' the Ladies' Auxiliary of the T-Birds, as seen when Rizzo goes to the big dance with Balmudo.
* CultClassic: The film eventually gained a cult following, with [[https://film.avclub.com/grease-2-is-actually-way-cooler-than-the-original-1798264518/ some fans]] even calling it superior to ''Grease''.
* HollywoodHomely: Michael, such a hopeless nerd. Kind of. The twins and Paulette both say that he is cute, it's more of that being a stuffy Brit, he is way out of touch with 60's American biker culture.
* ItsTheSameNowItSucks: Generally seen as a weak retread of the first movie.
* RetroactiveRecognition:
** Goose is a young Creator/ChristopherMcDonald.
** Michael is [[Franchise/JamesBond Bond]]. [[VideoGame/{{Nightfire}} James Bond]].
* {{Sequelitis}}: The original is a hugely popular 50s nostalgia funfest. This movie has only a few characters returning from the original (Frenchy, Eugene, the principal and her assistant, and the coach. All brief roles.) and introduces Sandy's cousin Michael in some weak attempt to connect the two movies. The plot is basically a GenderFlip of the first movie's plot and the results are... well, let's just say [[FanonDiscontinuity most Grease fans like to pretend it doesn't exist.]] Paramount planned two more sequels after this one, as well as a TV series. When ''Grease 2'' flopped, Paramount abandoned those plans. A new, straight-to-DVD sequel has been in the plans for Paramount for over a decade now.
* SoBadItsGood: This movie makes the first one look like Les Miserables by comparison. Among the changes: an inferior script, much less angst (and most of what is there qualifies as {{Wangst}}), far less actual sex, much more singing about sex. It's a good time!
* ValuesDissonance:
** The "Reproduction" number, a cringey song that makes light of date rape ("they change their tune when you get them in the backseat" "all they can do is say 'no no no no no no no no no!") complete with sexual harassment ("I got your 'pistil' right here!", ignoring the fact that the pistil is the plant's female reproductive organ).
** "Let's do it for our country" involves Louis saying he's going to fight into a war, while a bomb warning goes off (thanks to his friend helping out) implying they are under attack at that very moment. He uses this to get Sharon to "put out" but not only has Sharon said no before (off screen). She clearly doesn’t want to do anything with Louis being extremely freaked out through out the song while being coerced into sleeping with him. Thankfully she discovers it was a lie but that doesn’t change the fact that Louis wanted to sleep with her under false pretenses. She's justifiably hurt and mad when she discovers this however she's still dating him in the final musical number. He also gets away with what he did.
* WhyWouldAnyoneTakeHimBack: The T-Birds qualify.
** Johnny's clearly only with Paulette because he can't have Stephanie and Paulette doesn't seem to care at first. She is later extremely hurt and angry when he gets jealous over Stephanie (after her date with the cool rider). Paulette just wishes he would choose her. However at the talent show, she realizes she deserves better from him. So she calls him out for his behavior and tells him off for pushing everyone around and saying she’s the best girl he’s ever going to get, then she goes to perform.
** Sharon should have dumped Louis for what he did (and tried to get her to do) but it never happens.
