Faramir is one of the most iconic characters in the Lord of the Rings universe. In the book, the hero is shown as a kind and steadfast person. However, already in the film The Lord of the Rings: The Two Towers, he becomes a character who constantly prevents Frodo from completing his task.
Denethor also looks different on screen. He turned into a very cruel man, a real tyrant. And the fact that he always preferred one son to another even turned into a meme "But Boromir could do it." This is how Denethor met the news of any problems Faramir had.
Why Denethor hated Faramir in The Lord of the Rings
It is quite possible that the father disliked his son because his wife died in childbirth. This was a consequence of the terrible treatment between relatives that viewers could see in the films.
In addition, Denethor always noted that his eldest son Boromir is a natural leader who is happy to take part in all military campaigns. Compared to him, his brother seemed softer, not eager to take up the sword. The father considered such peace-loving behavior of the heir to be weakness. However, Faramir's tactics deserved recognition. He even managed not to succumb to the temptation of the Ring of Omnipotence, unlike his brother.
Why Gandalf is to blame for Denethor and Faramir's quarrels in The Lord of the Rings
This plot line was almost never shown in the films. However, readers of 'The Lord of the Rings' will remember that Denethor disliked Gandalf. He contemptuously called him a sorcerer and believed that he would help Aragorn eventually overthrow him from the throne.
That is why the character did not like the fact that Faramir was fascinated by Gandalf's teachings. Denethor did not miss an opportunity to criticize his son for becoming a follower of the sorcerer.
