They Copied It, So It Sucks!: It has often been accused of being a Recess rip-off, even though the only things the shows share are being late '90s animated series about kids in a school dealing with a mean teacher.
Toy Ship: Shareena and Emmitt. All the friends had histories dealing with each other's quirks, but a few of Emmitt's charismatic yet comically misled moments really brought out the snark in Shareena.
For the film:
Complete Monster: Sander Sanderson is initially presented as a pervert who constantly makes unwanted advances towards Riley Jones, and a classmate of Ione Rose and Clapton Davis. Brutally murdering the popular Taylor Fisher, attempting to kill Riley, and later butchering the athlete Billy Nolan, Sander feigns friendliness with his classmates while planning to kill them. Outraged by Riley's constant rejection, Sander kills exchange student Gord and Principal Karl Verge, then travels back in time to 1992 in order to convince a young Verge to eliminate the town of Grizzly Lake in an explosion with his help. When Riley and Clapton foil Sander's plot, he attempts to detonate the bomb himself, only succeeding in killing himself. In the altered timeline, Sander attacks Clapton and Riley, decapitating his implied sex partner Alexis when she walks in on him attempting to kill Riley for rejecting him. Lecherous, entitled, and contemptuous, Sander is a galling example of a possessive creep.
"Funny Aneurysm" Moment: One of the bullet points in Taylor's guide to not being a total reject states "your lack of faith in the durability of Kesha is disturbing." That joke became funny once Kesha did indeed fall from mainstream popularity only to became a lot less funny come 2016 once people learned precisely why her career flatlined so quickly. Then it became funny again when, come 2017, Taylor was proven right and Kesha enjoyed a Career Resurrection.
Similarly, the mention of Hoobastank in the "BITCH" acronym seemed like just a weird and dated reference when the film came out fast forward to 2017 and the release of Sonic Forces, which includes vocals by the lead singer of Hoobastank in its main theme.
Hollywood Homely: Toyed with. Riley's club foot and clumseyness may be a reference to the high school film cliche.
Fridge Horror: By the time Ray meets up with Wei in the Good Ending, the school is in ruins. Just how long was Ray going through that hellish loop?
Germans Love David Hasselhoff: The game is pretty popular on Mainland China and well-received, with many giving a respectful view of the political tones in the game. Mainland Chinese sales of the game account for roughly 70% of total sales.
Inverted later on, as the game was massively review-bombed by Chinese players after anti-government messages sneaked in by a developer were found on the studio's follow-up game, Devotion.
Jerkass Woobie: Ray, who gets more and more unstable as the game progresses. She sold out her classmates and teachers out of petty, selfish jealousy, which resulted in the deaths or worse of them all and is never going to be allowed into Heaven, or even to be reborn, cursed to wander as a spirit forever. And that's if she gives the right answers at the end!
Unintentionally Unsympathetic: Mr. Chang is portrayed as a kind and caring person. But if his relationship with Ray really was reciprocated, then he was abusing his position as a counselor to take advantage of a vulnerable young girl one he's supposed to be helping with her issues, even! Doing so unwittingly helps cause the whole mess, but the blame is squarely placed on Ray's shoulders, instead of sharing it with the authority figure who abused his position. Also counts as Values Dissonance.
Values Dissonance: The relationship between Ray and Mr. Chang is treated as largely positive and healthy, and Ray is viewed as totally unsympathetic for what she did when it ended. However, this is a romantic relationship between a vulnerable teenager and the much older teacher/counsellor who was meant to be helping her with her family and academic issues; a relationship instigated by the teacher himself, no less. Players tend to view Chang as a problematic character to say the least.
To get the Golden Ending, you must answer the questions of Ray's lingered spirits correctly. One of the questions she asks is whether to "quietly accept" or "try to take them back". Most Western players would choose "quietly accept" and interpret it as taking responsibility for her actions, while "try to take them back" implies the opposite. However, as the game is heavily steeped in Buddhist themes (which the average Westerner might not be familiar with), the whole purpose of this part is for Ray to remember what she did back then, not what she would choose to do from now on, so the correct choice is actually the latter.
