Remakes only need to happen if the original movie had a good idea but a bad execution. The Princess Bride, Back to the Future, Goonies, etc. were all fantastic movies & don't need to be remade. The problem is that studio executives are focused on money, and remakes do produce results because they are ridiculous cash cows:
* Cindarella 2015: $100 million budget, $543 million box office
* Jungle Book 2016: $177 million budget, $966 million box office
* Dumbo 2019: $170 million budget, $353 million box office
* Aladdin 2019: $183 million budget, $1 billion box office
* Lion King 2019: $260 million budget, $1.6 billion box office
Even Dumbo, which only has a 50% audience score on Rotten Tomatoes, made $183 million over budget. The Lion King made literally a billion dollars over budget. Collectively, those 5 movies cost $890 million to make and made $4.462 billion, which translates out to over a $3.5 billion dollar profit. It's hard for any business-minded studio exec to say "well gee, we want to keep the romance & integrity of the original movies & not remake them" when over three billion dollars are on the table.
However, to me, the actors, collaboration, and original stories of stuff like The Princess Bride, Back to the Future, and the Goonies are what made them work. I'd prefer to see them not be remade. If they do want to continue the story with a well-done sequel or prequel or something like that, that's fine, but why ruin greatness? It's the question of money vs. art. In the Disney suite above, it's hard to say not a few extra billion in profit.
