- Angst? What Angst?:
- Despite being Anglican, Rahne doesn't seem to have any problem with being romantically attracted to Dani. Notably, she confessed to masturbating in the chapel booth, a somewhat less serious sin in Catholicism.
- Likewise, while three of the others angst about killing the people around them by accident, Dani never displays a horrified reaction to the fact that she was the one who killed everyone on her reservation. Especially considering that she tried to commit suicide before the fact came to light.
- Base-Breaking Character: Magik. Some consider her to be a racist, bigoted bully, while others say that she's the only character who was properly cast and the most memorable thing in the whole movie.
- Captain Obvious Reveal:
- Cecelia Reyes is the Big Bad, a position telegraphed as early as the first trailers. And for comic fans, the fact that her position gets hijacked by Demon Bear.
- Also, the fact that Dani's mutant powers allow her to bring other people's worst fears to life. Not only is this common knowledge to anyone that's a fan of the comics (read: most people watching the movie), but even if you didn't know, you could guess almost immediately.
- Epileptic Trees:
- Some fans have already theorized that the facility in the film is an extension of Transigen, the company from Logan, and that the characters will be linked to their experiments that resulted in Laura. Connections to the Workshop from Deadpool (2016) and Essex Corp. from X-Men: Apocalypse, either as alternatives or by extension, also come up. Those who speculated the involvement of Essex Corporation were correct.
- Following the film's second delay, some fans began to speculate that the film — and quite possibly Dark Phoenix — could go directly to a streaming service that Disney owns (which has materialized into Disney+), provided that their merger with 21st Century Fox goes through before the movie's intended release date in late 2019. This would be similar to what happened with The Cloverfield Paradox. This line of speculation was finally debunked in April 2019, when Disney included the film on their 2019 slate for theatrical releases (although Disney would later opt to reschedule the movie to April 2020, and then to delay it until August 28 due to the COVID-19 Pandemic, during which multiple theatrical movies have been moved to streaming-first release).
- Fandom Rivalry: With the Marvel Cinematic Universe, especially that this film takes a Darker and Edgier Superhero Horror approach to the X-Men franchise. The fact that the Disney-Fox merger eliminated the chances of Josh Boone's trilogy didn't help.
- The Firefly Effect: Like with Dark Phoenix, the Disney-Fox merger, and Fox's indication that there will be no sequels to make way for a total X-Men movie franchise reboot, has dampened excitement for the project. However, the infamous delays to the project have also paradoxically created interest in the film that wouldn't otherwise be there, so it has that over its predecessor.
- Memetic Mutation: Any mention of the movie, positive or otherwise, tends to get met with jokes about the infamous delays that have pushed the film back significantly. One promotional video even had a tongue-in-cheek reference to the delays by stating that "nothing will stop the New Mutants", and a later promo explicitly made light of the delays and the social media reaction to them. When the film was finally released on August 28th 2020, many joked that it was some kind of prank and the movie was still yet to be released. Even the movies final poster carried the tagline Hell has frozen over.
- Older Than They Think: This isn't the first Marvel horror movie; that honor goes to 1998's Blade. However, this is the closest we will ever get to a traditional Haunted House horror movie made by Marvel Entertainment, while Blade was action-oriented and bordered a Martial Arts Movie.
- So Okay, It's Average: By far the most common consensus once people finally got to see it, with a promising story being let down by one-note characters. And of course, the fact that anticipation had been building for years didn't help at all.
- They Changed It, Now It Sucks!: Illyana's Adaptational Jerkass; note that while her character is typically a jerk in the comics, she has never been as casually racist as she is in the film, nor is her banter ever so mean-spirited (at best she's The Gadfly to her friends, but never an outright bully). There's also some discomfort with the decision to make her a survivor of child sex slavery, seemingly to disconnect her from her brother (who is the X-Man known as Colossus), especially as her backstory of being raised in Limbo was still on the table given Limbo's inclusion.
- Took the Bad Film Seriously: The general consensus among critics is that Maisie Williams and Anya Taylor-Joy are the only cast members who are desperately trying to give some depth to the shallow script.
- Ugly Cute: Rahnes midpoint between her wolf and human forms would have probably looked genuinely scary on anyone who wasnt Maisie Williams.
- Unfortunate Implications:
- There was controversy about the casting of Henry Zaga as Sunspot; while Zaga is Brazilian like Sunspot, he is white whereas Sunspot is (or at least was) a dark-skinned Black Brazilian hero. Most of the anger was initially directed to Marvel Comics as opposed to the movie producers since the comics have been steadily whitewashing Sunspot since the 1980s, going from black into the more stereotypical brown (to the point where casual fans do not know that Sunspot is a black character). Unfortunately, the director of the film dug himself deeper when he said that he cast Zaga as Sunspot because he looked like he came from a wealthy family, ignoring that Sunspot, in the comics, has a black father who is rich. He also said he didn't consider the racial issues important to the story, an especially tone deaf statement, considering he's directing an X-Men movie.
- The fact that the cast is missing Karma, the Vietnamese lesbian who was a founding member and the original team leader, only adds to that. Boone has suggested she will appear in a sequel, but it's very questionable that she wasn't perceived as important enough to be introduced from the beginning, not to mention the fact that — with a complete X-Men reboot looming in the near future — the very existence of such a sequel is extremely unlikely even if the film is successful. The fact that Dani and Rahne were hit with Adaptational Sexuality only serves to rub salt in the wound — why couldn't one of them have just been replaced by the New Mutants member who was already canonically gay?
- Some of Illyana's edgy-bad-girl "banter" with Dani has been called out as actually just being racist insults, like calling her "Pocahontas" or saying "your people love buffalo, don't you?" (when offering her a buffalo chicken wing). There's a difference between being a Jerk with a Heart of Gold slash Token Evil Teammate who is spiky and rude before she warms up to someone, and slinging around racist stereotypes. Additionally, that's not something Illyana does in the comics, so there's not even that excuse.
- Unintentionally Unsympathetic: Illyana, for some. She was clearly just meant to be an edgy badgirl who banters with Dani, but her choice to invoke Dani's Native American heritage with repeatedly racially-based insults just made her come off more as a bigoted bully.
- What Do You Mean, It's Not for Kids?: Despite being a PG-13 movie, the dark trailer makes it very explicitly clear this film isn't for kids, unless they want to be traumatized by said film's horror imagery. They even made a "G-Rated trailer" in Taiwan with all jump-scares blurred out just to show parents how scary this film is. Child sex slavery and religious abuse are part of some of these characters' backstories.
YMMV / The New Mutants
