These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: About Van Pelt. Is he perhaps a sociopath who hunts human beings just for pure sadism, or maybe he's a Noble Demon who just follows the game's rules and could also be redeemable if he had the chance? There's also another, infinitely more horrifying interpretation. What if Van Pelt was just another poor soul trapped in Jumanji like Alan was, but was either never rescued or was killed before finishing the game, leading to him becoming twisted into part of the game itself?
The animated series suggests the latter is certainly possible, as whoever kills Van Pelt risks taking his place.
Fridge Horror: What would've happened if Sarah had rolled the dice after Alan was sucked into the game but didn't get the five or eight needed to free him? What if she had been killed by the next horror that emerged (which was a very real risk)? Would the game be stalemated forever with Alan stuck inside for the rest of his life?
Harsher in Hindsight: The background scenes describing the effects of the giant mosquito bites to unsuspecting victims make it all the more scary when one thinks of the West Nile Virus.
Love It or Hate It: It literally scored a 50% from Rotten Tomatoes, with as much critics for it as there were critics against it.
Really none of the CGI has aged well, most CGI doesn't after all. However the monkeys are arguably the most glaring example. They stood out even during the time of release due to their poorly rendered fur. But then again most of the animals (CGI or otherwise) had a slightly stylised look, as opposed to photo realistic, so maybe they were supposed to look a little off. Still even if you're kind enough to accept that, it doesn't really excuse all that much. As you can see below.
In a scene that shouldn't even have required special effects. When Van Pelt hands over the gold coins mentioned in Screw the Rules, I Have Money!, his arm and the coins falling has a very strange after-image look to it, as if they're made of sand.
Although, considering this happens a few times with Van Pelt having occasionally blurry movements, and the animals, even puppets, also have the same type of blur at times, this could have been done on purpose, a nod to the fact that they aren't real and don't belong in our world to begin with. It's worth noting that when Jumanji is declared, Van Pelt begins to dissolve into a sand-like substance as he's pulled back into the game.
The spiders toward the end of the film. The budget to the film was dangerously close to going over so they had to cut back and relied on puppets for the scene. It's incredibly obvious once they appear, especially since they move in a very jerky, wooden way (Picture that way a child makes dolls move, moving it forward while bouncing it up and down to simulate walking.) Never stops them from being any less terrifying...actually, it might make them even scarier, since it gives the impression that they're very unnatural spiders more dangerous than the norm.
