The question was "Is Queen Anne, as depicted by Olivia Colman in "The favourite", a fair representation of the real Queen Anne?"
This answer was written by Catalina Fometici on Quora, who obviously did her homework:

Not really. That was a caricature, mostly based on Lady Churchill’s memoirs. First of all, she was not gay. Queen Anne was married to prince George of Denmark and loved him dearly, they were faithful and devoted partners until the end. They had 17 children together. es, all their children died young, or were born dead, or were miscarried, but still. Also, they slept in the same bed during their marriage, which was very unusual at the time for an aristocratic couple, let alone royal. When he died, the queen was devastated and would not let go of his body. Lady Churchill had to remove her by force from that room. But prince George was very much alive during most of the events in The Favorite. Lady Churchill was not gay either. Born Sarah Jennings, she came to court as a maid of honor for Mary of Modena, second wife of king James II. She fell in love with John Churchill, Duke of Marlborough, in 1675, when she was 15 and he was 25. He was impoverished; his father wanted to have him married to Catherine Sedley, a very wealthy lady and a mistress of James II. But he loved Sarah. They married in secret in the winter of 1677.

Queen Anne and lady Churchill became friends in 1675, when they were both very young. Sarah was a very bright and intelligent woman, had a great political sense, would always speak her mind, and the queen would often seek her advice. She was created Mistress of the Robes, Groom of the Stool, Keeper of the Privy Purse, and Ranger of Windsor Great Park; basically she had the highest offices a woman could have at court (and some only a man could hold), she was the second most powerful person in England. She had control over everything regarding the queen, over her finances, over the people admitted in the queen’s presence. But she didn’t speak in the queen’s name, as shown in the movie; queen Anne was perfectly capable of speaking herself and defending her own ideas. Actually, lady Sarah would only rarely appear at court.

They clashed over politics, mostly. Queen Anne was a Tory, while Sarah was a Whig. The Whigs had supported Sarah’s husband during the war, and they hoped to use her position as a favorite of the queen in order to gain influence. But queen Anne disliked the Whigs, saw them as radicals and a threat to her royal prerogative. She was more interested in the church and religion. She refused to appoint Sarah’s son-in-law, a Whig, be admitted in the Privy Council, so lady Sarah used her friendship with the Earl of Godolphin, the Lord Treasurer, to secure the position for him. By this time, the queen said she didn’t feel like Sarah and herself could ever be true friends again.

Also, there was a clash of personalities.
It is true lady Churchill was dominating the queen (and everyone else, actually) with her powerful personality. She was bold, witty, outspoken, and gave no flattery. Still, she was charming, vivacious, and was admired by many.

Queen Anne was religious, shy and sensitive. In her memoirs, lady Churchill wrote: “She certainly meant well and was not a fool, but nobody can maintain that she was wise, nor entertaining in conversation. She was ignorant in everything but what the parsons had taught her when a child... Being very ignorant, very fearful, with very little judgement, it is easy to be seen she might mean well, being surrounded with so many artful people, who at last compassed their designs to her dishonour.” She also suffered from depression over the loss of her children and failed pregnancies; she expected kindness from her best friend. But Sarah wasn’t very good at showing kindness and empathy, and was away from court most of the time, so the queen turned to lady Abigail for comfort. Baroness Masham, born Abigail Hill, was a cousin of lady Sarah, from an impoverished side of the family. Sarah took Abigail into her own household, at St. Albans. Then, in 1704, Abigail joined the queen’s household and was created Lady of the Bedchamber. No, Abigail was not thrown into mud when she came to court, nor did she scrub floors. She did work as a servant, for Sir John Rivers of Kent, but that was before Sarah became aware of her existence. Tired with Sarah’s constant political lectures and her absence from court, the queen became close with Abigail. Unlike Sarah, Abigail was not talking politics, and showed the queen the kindness and compassion she most needed. Sarah didn’t take this friendship well, and neither did she like it when she was dismissed from court, after she insulted the queen. Her offices, including Keeper of the Privy Purse, were given to Abigail.
