- Darkness-Induced Audience Apathy: The cast are hardly likeable, with the main character using the box to make wishes despite getting the memo that the box kills people. The worst part? Even if you rooted for Claire to beat the box via a Reset Button Ending, she still dies anyways and makes the overall movie pointless as someone else just picks up the box anyways.
- Ensemble Dark Horse: Meredith is well-liked, mostly because despite her roughness, she's the only one to rightfully call Clare a bitch for keeping a mystical item that kills people when wishes are made. Most viewers could rest easy knowing that the last wish was able to resurrect Meredith from her death earlier in the film.
- Fanon: It has been commonly accepted among fans that this film takes place in the same universe as the Conjuring film series and its spin-offs due to the fact that the director also directed Annabelle.
- Narm: Pretty much the entire movie qualifies, but some special moments are listed below:
- The movie's soundtrack is terrible, consisting of music that sounds like it could have come off a Now That's What I Call Music! compilation.
- Jonathan still giving in to his compulsion to hoard and dumpster dive for some reason, even after Claire inherits her wealthy uncle's fortune.
- One of Claire's wishes is for her father to stop dumpster diving and be a cool musician. Cue a very clichéd scene of Claire and her friends fawning over her father playing the saxophone like in a 70s sitcom.
- The fact that Claire wishes that Paul would fall madly in love with her is particularly hilarious in that it's so blatantly a very stupid wish that will come back to bite her in the ass.
- The scene where Paul takes Claire's rejection badly is difficult to take seriously due to his reaction being... to simply cut himself instead of doing something more drastic like committing suicide, after he claims that he can't live without her. There's also the fact that Claire's shocked gasp in response to what happens is clearly a Stock Sound Effect. This entire sequence is also never brought up again.
- The film's attempts at showing Claire's mental state in some parts amounts to merely desaturating the colors when she's unhappy and then restoring the saturation when she's happy, as if the filmmakers felt that her facial expressions weren't sufficient.
- Claire's mental breakdown toward the end is nigh-impossible to take seriously due to Joey King's hilariously over-the-top performance.
- Nightmare Retardant: Most deaths in the film, which isn't helped by how they're clearly tailored to get the film a PG-13 rating, as well as being largely caused by the victims' own stupidity. Particularly hilarious deaths include Uncle August really clumsily slipping in the tub and hitting his head on the edge of the tub and finally doing himself in by banging his head on the nozzle and Clare's body flying after getting hit by Darcie's car.
- The Scrappy: Claire. Despite being the main character, viewers found themselves unable to sympathize with her when she continued to use the box for herself even after knowing that its effects kill people after making a wish.
- Snark Bait: The movie has been the butt of mockery for being yet another Cliché Storm horror movie with loads of unintentional hilarity, particularly in the death scenes. The fact that the director also directed the similarly-mocked Mortal Kombat: Annihilation and Annabelle doesn't help.
- So Bad, It's Good:
Wish Upon is neither scary nor original, but its fundamental flaws as a horror movie may make it destination viewing for after-midnight camp genre enthusiasts.
- This appears to be the overall critical consensus for the film, as indicated on its Rotten Tomatoes page:
- Tainted by the Preview: The film's trailers state that it is directed by the director of Annabelle (another poorly-received horror movie), and said director also directed the critically panned Mortal Kombat: Annihilation. This led viewers to decide not to see the film, which wasn't helped by the trailers including many overdone horror clichés and giving away significant plot details.
- What an Idiot!:
- For some reason, after she is down to her last two wishes, Clare never considers trying to wish for the box to immediately undo all of the evil it has done and destroy itself on the spot before it can even kill someone.
- It may or may not have worked, but the fact that Clare did not even try seeing if she could exploit the wishes (depending on rather or not they had a limit) by seeing if she could wish for the counter to reset itself or if she could wish for the box to no longer kill people after a wish is made. She also does not try to give the box to Ryan to see if the counter would reset itself when given a new owner (if it didn't remain unusable to anyone except her until she made her last two wishes), and if it did, seeing if he could make wishes for her that would undo the damage that had been done. The two of them really should have tried to figure out all of the details about how the box and its wishes worked so that they could figure out what was the best way to undo all of the damage that had been done.
- Even if the wish box wasn't actively malevolent wishing that Paul would fall "madly" in love with Clare is still a very poorly worded wish.
- Not to mention the fact that Darcie's friends (Read Minions) started a Go Fund Me for Darcie and when Clare and her friends (Darcie's main victims) refused to support it.
- Let’s not forget that those who did die from the wishes, often died from their own stupidity, such as Clare’s father standing on a chair while cutting down a branch with a chainsaw.
YMMV / Wish Upon
