History YMMV / TomAndJerryWillyWonkaAndTheChocolateFactory

** The scene at the end where [[spoiler:Wonka hands ownership of the factory over to Charlie]] is an iconic SugarWiki/HeartwarmingMoment in the original film, but here, after saying his iconic line, Wonka makes a [[https://i.imgur.com/PgK9IvQ.png truly bizarre smile]] that's silly enough to immediately ruin the scene.

* ViewerGenderConfusion: Tuffy's voice is unisex and childish. It sounds somewhere between Creator/KathSoucie's other roles as Phil and Lil from ''WesternAnimation/{{Rugrats}}''.
* WTHCastingAgency: The voice casting choices for the four brats raised a few eyebrows, considering none of the actresses were known for voicing characters in that age range -- or in the case of the ones who voice Augustus and Mike, male characters, ''period''. That being said, Emily O'Brien (Veruca) was actually considered to have given one of the better performances in the film.

* {{Narm}}: Has its [[Narm/TomAndJerryWillyWonkaAndTheChocolateFactory own page]].

* AssPull: The movie keeps the 1971 film's ending reveal that the "Mr. Slugworth" Charlie meets was [[spoiler:actually Mr. Wilkinson, [[GoodAllAlong one of Wonka's employees that was sent to test the children]]]], but this perfectly fine twist from the original movie [[AdaptationInducedPlotHole is rendered completely nonsensical one in this one]] due to Slugworth having a [[AscendedExtra much more prominent role in the plot]]. Instead of the stoic and mysterious figure he was in the original, Slugworth is portrayed as [[ObviouslyEvil a cackling madman]] and [[spoiler:even keeps up this villainous façade with Tom, Jerry, and Tuffy [[note]]Which is not helped by the fact Tuffy also works for Wonka, and would surely know about this fake Slugworth and his role in Wonka's plan[[/note]] when he could have easily explained to them that Charlie wasn't in danger and sent them on their way]]. The movie's attempts to explain Slugworth's actions here [[VoodooShark end up falling flat and simply raise even more questions]].

* AudienceAlienatingPremise: Some people found the entire premise of remaking the '71 version so close after Wilder's passing to be an alienating choice let alone mixing Tom and Jerry in with it.

* TheyWastedAPerfectlyGoodCharacter: There's not really much of a reason for this being a Tom and Jerry film. They do their antics and fights during major scenes that can even end up abruptly destroying the story's tone, they oppose Slugworth on new scenes that add nothing to the plot besides attributing to the AssPull even more later on about [[spoiler:Mr. Wilkinson's SecretTestOfCharacter making even less sense for his seeming evilness]], and that's really it. Occasionally they do intervene in certain scenes like getting the quarter Charlie needed for the golden ticket Wonka Bar, but that means altering pre-existing story beats to shoehorn in the pair's involvement, and in other cases the actions they do take like stealing Wonka Bars ''ends up being undone and not influencing the plot''.
* TheyWastedAPerfectlyGoodPlot:
** Really, an AnimatedAdaptation of ''Charlie and the Chocolate Factory'' could easily work. Just not a ShotForShotRemake of the 1971 film with Tom and Jerry thrown in.
** Also in relation to the previous movie, ''[[WesternAnimation/TomAndJerryBackToOz Back To Oz]]'' had done some damage control by actually mixing in other elements from the Oz books into the MGM film-inspired world. This, coupled with the original title having Charlie's name instead of Wonka's, led to some fans thinking this movie would have mixed more elements from other things than the '71 film. While there are a few, the film mostly plays it straight to the '71 version that already has its own BrokenBase in the fandom of the original book. Needless to say, this came off as a disappointment to some and others thought it was just plain lazy on the creators' part.
