YMMV / Wish Upon

  • Ensemble Darkhorse: 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.
  • Nightmare Retardant: Most deaths in the film. In particular is 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: Clare. 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.
  • So Bad, It's Good: This appears to be the overall critical consensus for the film, as indicated on its Rotten Tomatoes page:
    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.
  • 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 cliches.
  • 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.
