The Harry Potter series has been the best stories and franchises of the past few decades and there is probably nothing we would do to change in it. The series seems perfect to us but there were some things that should have been added to the movies to fill the gaps that were created because of all the cuts made:
1. Neville Longbottom’s parents:
One of the most tragic scenes in the series is this scene from Order of the phoenix where Harry finds out the true state of Neville’s parents. Alice and Frank Longbottom were tortured by the use of the cruciatus curse by death eaters such as Bellatrix and Rodolphus Lestrange and Bartemius Crouch Jr to an extent that they lost their minds and were admitted to St. Mungo’s Hospital.
2. Pettigrew’s death:
In the movies we never got to know what happened to the filthy Wormtail but in the book his death is rather interesting. When Harry and Ron were put in a cellar in Malfoy Manor, wormtail kept a watch on them and later he was the one who released them too. This act of redemption on his part becomes his doom as his fake hand that was given to him by Voldemort strangles him when he goes against his master.
3. Ariana’s death:
The movies don’t focus much on Dumbledore’s back story but the final book gives us an insight into Dumbledore’s youth and his friendship with Gellert Grindelwald. Grindelwald makes Dumbledore indulge in dark magic and after a while Dumbledore realizes that he was blinded by his love for Grindelwald and this ends with a duel in which Dumbledore loses his younger sister Ariana and blames himself for it.
4. Petunia’s letter:
Those who haven’t read the books don’t know why Petunia was so bitter towards the wizarding community and her sister. When Lily got her Hogwarts letter, Petunia was miserable at the thought of losing her sister as well as the fact that she would not be able to experience the magical world like her sister. She wrote a letter to Dumbledore to admit her into Hogwarts along with her sister but she never got her wish granted.
5. RAB’s quest for the Horcrux:
Another great scene from the books is that of Regulus’s quest for Slytherin’s locket with the help of Kreacher. Regulus Black who was also a death eater tried to defy Voldemort after things got too far by replicating the locket after finding the real one. Regulus dies in the process of procuring the real locket and does not live to see it get destroyed.
