One of the novels often considered among the worst in the fantasy genre on Goodreads could be 'Twilight' by Stephenie Meyer. Many critics feel that its take on vampires and werewolves is rather simplistic and the writing style lacks depth. However, it's also extremely popular, which shows the divide between popular and critically 'good' in the fantasy genre.
I'm not sure of specific titles always listed as the worst. But sometimes, books with inconsistent world - building end up in this category. If a world is supposed to be based on a certain set of rules for magic or society, and those rules keep changing randomly, it makes for a bad read. It's like building a house with a different blueprint every day.
One of the worst could be 'Twilight' by Stephanie Meyer. While it has a huge fan base, from a pure fantasy perspective, it has a very weak world - building. The vampires are more like sparkly humans rather than the traditional, complex and often menacing creatures in classic fantasy. Also, the plot is mainly centered around a love triangle which overshadows the fantasy elements.
Some great goodreads fantasy novels include 'Throne of Glass' series. It features Celaena Sardothien, an assassin with a complex character arc. 'Mistborn' by Brandon Sanderson is also highly regarded. It has an intricate magic system and a great plot about overthrowing an evil empire. Then there's 'The Lightning Thief' which is the start of the Percy Jackson series. It combines modern world with Greek mythology in a really fun way.
Some of the top - rated ones include 'A Court of Mist and Fury' which continues the story from 'A Court of Thorns and Roses' and delves deeper into the relationships and the fantasy world. It has a very high rating on Goodreads. 'The Winner's Curse' is also highly rated. It combines a unique fantasy setting with a relationship that has many twists and turns. And 'The Grisha Trilogy' as a whole, especially 'Siege and Storm', is very popular among Goodreads users for its great blend of fantasy and romance.
The 'Eragon' series is sometimes considered bad in the YA fantasy genre. The plot is quite derivative, borrowing heavily from other established fantasy works. The writing style is also a bit clumsy at times, with descriptions that can be overly long and not very engaging.
I think 'The Mortal Instruments' series has some issues. The plot gets really convoluted as the series progresses. There are so many characters and sub - plots that it becomes hard to follow. And the world - building isn't as consistent as it could be.
One great fantasy romance novel on Goodreads is 'A Court of Thorns and Roses' by Sarah J. Maas. It has a captivating plot filled with fae lore, a strong female lead, and a steamy romance. Another is 'The Cruel Prince' by Holly Black. It's set in a world of faeries and features a complex relationship between the main characters that's full of intrigue and passion. And 'Shadow and Bone' by Leigh Bardugo also combines fantasy elements with a touch of romance in a unique and engaging way.
One way to find good goodreads fantasy novels is to follow some of the popular fantasy authors on Goodreads. They often recommend other books in the genre. Another method is to join Goodreads groups dedicated to fantasy novels. There, members discuss and recommend various books. You can also search for fantasy novels that have won awards, as these are often of high quality.
Well, 'The Selection' is often regarded as one of the not - so - great YA fantasy novels. It has a rather shallow concept where girls are basically competing for a prince in a very contrived way. The characters lack depth and the plot doesn't really offer much in terms of original ideas.
