The extremely popular theory that Courtney and Whitney are, in fact, speaking the truth when they describe Missy as an Uber-Dyke, and that therefore the ending is a classic case of Did Not Get the Girl, with a side order of I Want My Beloved to Be Happy.
Whitney's little sister Jamie giving a lackluster tryout, despite the other girls hyping her up. Is Whitney just blind to her sister's badness? Or is Jamie normally much better and she was just nervous trying out in front of the older girls? Do they just want her because she's a useful prop? Or does Whitney want her because Jamie won't upstage her?
One of the few things all six movies have in common — several name actresses dressed up in cheerleader outfits that show plenty of skin. Notably the first film's outfits Bare the Midriff — something which is not allowed on high school teams.
And of course the car wash scene in the first movie, getting Kirsten Dunst and Eliza Dushku into bikinis.
Cliché Storm: Most of the sequels do retreads of the first film's plot, usually with an anti-racism Aesop tacked on.
Designated Hero: You're supposed to root for the Clovers as much as, if not more than, the Toros, but their attitudes make that very difficult. Even Isis comes off as a real bitch until the end of the movie.
First Installment Wins: The term "the original and best" is widely considered to apply with Bring It On, although Bring It On: All or Nothing is felt to be the best of the sequels (in part becauseof who appears). To be fair, all the films are stupid and fun to watch. But the original is genuinely good and charming.
There's a Buffy the Vampire Slayer reference, clearly as a nod to Eliza Dushku's role as Faith. Clare Kramer would later star as Glory in Season 5.
If you're a Sabrina the Teenage Witch fan, seeing Lindsay Sloane as Big Red is hysterical. On Sabrina, Lindsay played Valerie - a neurotic wannabe who was desperate to be popular, frequently sucked up to the Alpha Bitch and made it onto the second string cheerleading squad.
Hollywood Pudgy: One of the cheerleaders from the first movie (and the third one as well) is repeatedly criticized for having a rather large backside. She's not that much more heavy than any of the other girls on the squad.
In Name Only: A musical titled Bring It On went on tour in 2011, and appeared on Broadway for a spell in 2012. Though it was advertised as Bring It On: The Musical and is about cheerleading, with some racial elements thrown in, it otherwise has nothing to do with any of the movies. However, considering none of the movies themselves having anything to do with each other, apart from the general premise of "cheerleading + hints of racial elements," it still fits right in.
Les Yay: Torrance and Missy in the first movie have a Romantic Two-Girl Friendship, Torrance defends Missy from the other cheerleaders, and their friendship is given slightly more screen time than Torrance's budding romance with Cliff. One of the most blatant cases is this scene, where Torrance seems more excited than the guys about Missy in her cheerleader uniform.
Torrance: TAKE IT OFF!
Memetic Mutation: The first film brought the terms "jazz hands" and "spirit fingers" into the popular lexicon.
Values Dissonance: There is some casual homophobia on the part of some characters. While Whitney and Courtney calling Missy an "uber dyke" is meant to show them as bullies, there is some of this underlying Torrance's relationship with Aaron. He's a fellow cheerleader, quite the Camp Straight and shown as a Romantic False Lead - in contrast to the Cool Loser Cliff. Aaron's college girlfriend even laughs at him when she finds out he was a cheerleader.
The Cheerleader was a popular trope in the 90s, painting cheerleaders as either Alpha Bitches or ditzy whores - which does have a few Unfortunate Implications since it's a female-dominated sport. The movie shows cheerleading as a genuine athletic pursuit, Missy learns that it's far more challenging than she thought, and the team are shown putting a lot of time and effort into choreographing their routines. Despite the film's goofy tone, it treats cheerleading in a positive way. It treats male cheerleaders pretty well too, rather than stereotyping them all.
Indeed, in spite of the above Values Dissonance with the casual homophobia, at the end Les, who had been established as gay early on, has a Meet Cute moment with a male cheerleader on one of the other teams at Nationals, a specific choice to give this moment to the gay character instead of having it be another straight character (like fellow male cheerleader Jan).
The anti-racism Aesop is thankfully not too Anvilicious and handled in a good way. No one in the movie is overtly racist but they do become aware of the system in place - Big Red stealing the Clovers' routines because they're too poor to afford to go to competitions parallels abuse of privilege. Torrance tries to invoke White Man's Burden by lending the Clovers money to make it to the competition, but they turn it down and raise the money themselves. But they face each other as Worthy Opponents. One critic said that the film suggests "race relations could be smoothed and transcended through level-playing-field sports competitiveness."
