In the end of the Aladdin story, Aladdin uses his final wish to free the Genie. He marries Princess Jasmine and they live happily ever after in Agrabah. The Sultan also realizes that Aladdin is a worthy man for his daughter.
In the end of Aladdin's story, Aladdin manages to defeat Jafar. He uses his wits and the power of the genie's magic (but in a good way). Aladdin also wins the heart of Princess Jasmine, and they end up together. The genie is set free as Aladdin wishes, which is a very heart - warming part of the ending.
Well, the ending credits of Toy Story 4 do have explanations. They might give credit to various people involved in the production, offer insights into the making of the movie, or contain sneak peeks related to the franchise.
One possible alternate ending could be that Jafar actually manages to outwit Aladdin in the final battle. Instead of Aladdin winning and getting the girl and the kingdom, Jafar takes over completely. He turns the kingdom into a dark and desolate place, with all the citizens living in fear. Aladdin is banished to the desert, and Jasmine is forced to be Jafar's prisoner. This would be a much darker and unexpected ending compared to the original.
An interesting idea could be that the Genie accidentally grants a wrong wish. Let's say Aladdin wishes for something to help him defeat Jafar, but due to a miscommunication, it backfires. This leads to a situation where Aladdin has to find a way to reverse the effects of the wrong wish and still defeat Jafar. It could add a lot of comical and tense moments to the story. For example, he might be turned into a small animal for a while and has to rely on his wits and the help of his friends in this new form.
The ending of Aladdin reflects the moral values of kindness and selflessness. Aladdin freeing the Genie shows his selfless side. This act of kindness is rewarded as he gets to marry Jasmine and live happily. It also shows that true love can overcome class differences, as Aladdin, a commoner, marries a princess.
