The Brontës are the Pringles of literature: once you pop, you can’t stop

Varsity discusses Wuthering Heights.

Emily Bronte is the elusive and mysterious author of Wuthering Heights. It is her only novel, as she died just one year after its publication. Even though she didn’t have the chance to write another novel, Wuthering Heights is a timeless testament to the incredible (and unsettling) power of her writing.
Safe to say, Wuthering Heights didn’t get off to the best start. In 1850, following Emily’s death, her sister Charlotte wrote a preface to the book. Describing it as a novel 'hewn in a wild workshop’ out of ‘homely materials,’ Charlotte wrote that Emily ‘did not know what she had done’ in exploring such outrageously un-feminine topics as twisted desire and curious, unearthly hatred. Charlotte then proceeded to label her sister ‘a native and nursling of the moors,’ adding that had she lived in the town, her writing would have ‘possessed another character.’ Granted, had she written in a town, her novel may have been a little more to Charlotte’s liking. Yet as an undeniable child of nature, the novel could not be so morbidly bewitching if it weren’t for the lonely and unusual companion it found in the Moors. [...]
Following Emily Brontë’s death, five reviews were found on her desk. One anonymous reviewer in Douglas Jerrold’s Weekly Newspaper (1848) said:
‘Wuthering Heights is a strange sort of book,–baffling all regular criticism; yet, it is impossible to begin and not finish it; and quite as impossible to lay it aside afterwards and say nothing about it.’
They couldn’t have been more right. (Scarlet Rowe)

While The Film Magazine has ranked four film adaptations of Wuthering Heights. According to them the best is Wuthering Heights 1970.

1. Wuthering Heights (1970)
Finally, a version of Wuthering Heights where the actors actually sound Northern…
This is not the only reason for this 1970 version to be in the top spot on our list, but it is very important that the actors are believable as Yorkshire folk in what is a story so strongly defined by its Yorkshireness.
Most importantly as regards 1970’s Wuthering Heights taking the top spot, there is genuine passion between the leads. This time Heathcliff is played by James Bond himself, Timothy Dalton. Not only does the connection between the characters feel genuine, but there is an equality between the sexes that seems lacking in the other versions – Cathy, played here by Anna Clalder-Marshall, does not feel small next to Heathcliff like in the other movie versions of the story.
Their love for each other is clear from the beginning, the only issue with this being that the film heavily implies that Heathcliff is actually Mr Earnshaw’s illegitimate child and therefore Cathy and Heathcliff are half brother and sister. But we try not to think about that too much…
Cathy’s reasons for marrying Edgar are because of her love for Heathcliff, to get him away from Hindley. This version best portrays that, ensuring the narrative makes more sense, getting us on side with the pair uniting, the couple finding their happy ever after.
Appropriately, this 1970 release also has the most satisfying ending, with the gothic sensibilities of the 1939 version incorporated to have an unconventional romantic conclusion; one that feels all the more impactful because of how believable the central relationship is.
Simply, no other Wuthering Heights built such a believable relationship as in this version, and while other iterations featured stronger individual elements, it is this Robert Fuest directed adaptation that is the most complete and enjoyable of the bunch. (Annice White)

Do read about the other three.

The Guardian is listing the 100 greatest UK No 1s and Kate Bush's Wuthering Heights is number 14.

It is sometimes worth remembering the incredible fact that Bush wrote Wuthering Heights when she was 18 years old, though perhaps its keen ear for adolescent angst is part of what makes it so special. She had been inspired by an old television adaptation of Emily Brontë’s novel, which led her to seek out the book. Written from the perspective of the ghost of Catherine Earnshaw, a young woman pleading with the brutal Heathcliff, whom she loves and hates, to let her soul into the house, the song is a gothic melodrama that builds until it is thick with intensity. It is a magnificent achievement, though the writing of it was seemingly painless. “Actually, it came quite easily,” Bush recalled later, telling the story of a single moonlit night at the piano. The vocal was said to have been recorded in a single take. Bush found out that she and Brontë shared a birthday, and the fates were aligned. (Rebecca Nicholson)

Another article in The Guardian mentions the song as well. In a less scholarly light, though:

We know this isn’t over yet, so let’s focus on looking after ourselves and looking out for each other, and for those who are left out when people state that we’re all in this together. Then throw out your goal-setting diary, roll yourself up in a red blanket and perform Kate Bush’s Wuthering Heights for your cat. Whatever continues to get you through. (Deirdre Fidge)

Also, according to Marie Claire, this is one of the 'best quiz questions for your next virtual games night':

1. Kate Bush famously sang: ‘Heathcliffe [sic], it’s me Cathy/ I’ve come home/ I’m so cold/ Let me in through your window’ – but what famous author wrote the novel that was the song based on? (Jadie Troy-Pryde)

Book Riot recommends '20 Must-Read Free Classics You Can Find on Project Gutenberg' such as these two great novels:

The Tenant of Wildfell Hall by Anne Brontë
Could you read Jane Eyre and Wuthering Heights on Project Gutenberg? Yes, you could. I won’t stop you. But consider first tackling this willful, ahead-of-its-time doorstopper from the youngest of the Brontë clan. Fleeing her alcoholic husband, Helen Graham strikes out in search of a life of independence for herself and her son, a journey with a gothic setting and slow burn romance.
Villette by Charlotte Brontë
The Brontës are the Pringles of literature: once you pop, you can’t stop. Bending to that reality, indulge in the Jane Eyre author’s final novel, which documents the turbulent life of Lucy Snowe. The story is drawn from Brontë’s own life experience as a teacher in Belgium, and its heroine makes for an interesting context to Jane. (Nicole Hill)

Meaww discusses Jane Austen's Emma and claims that,

Similar to how 'Twilight' fan-fiction led to 'Fifty Shades of Grey' and 'Harry Potter' fan-fiction led to the 'Shadowhunters' series, 'Emma' gave rise to a major novel too. Charlotte Brontë was appalled by the treatment of Jane Fairfax and essentially wrote 'Jane Eyre' as a form of fan-fiction. (Neetha K)

However, if we take Charlotte at her word, she hadn't read Emma before Jane Eyre was published.

The Scotsman reviews the book Rebel Women, by Rosalind Miles.

What struck me most sadly about this book is that it has little to say about culture, save for a few dropped references to Austen, the Brontës and Mary Ann Evans (also known as George Eliot). (Stuart Kelly)

Ara (in Catalan) reviews Woody Allen's book Apropos of Nothing.

Per demostrar que als 84 anys encara té "grans llacunes", reconeix no haver llegit el Quixot, l’Ulisses de Joyce, la Lolita de Nabokov, Charles Dickens ni les germanes Brontë. Tampoc ha vist mai "una representació en directe de Hamlet", ni s'ha empassat cap de les versions d'Ha nascut una estrella ni de Ben Hur. (Jordi Nopca) (Translation)
