With so many forms of entertainment at our disposal, two seem to dominate this sphere — books, and movies. And if you combine them, you get a lot of book to movie adaptations — the ultimate form of entertainment. However, not every book adaptation becomes successful in the eyes of the audience. A book to movie adaptation can sometimes be a flop, same with a series. The failure is usually the result of the butchering of the original story and bad creative decisions on the filmmaker's side.
It’s no secret that some books are much longer than their adaptations. Some of the best book to movie adaptations (TV show adaptations included) are ones that correctly use the given material, cutting out the boring parts, and leaving only the fun or most important ones. But not everyone can do it. Many bad movies based on books follow the original material letter to letter. An adaptation like this removes the whole creative side of the film, making the final product feel a bit bland.
If you want an adaptation to be a box office smash, you have to understand the deeper context of the book. Books made into movies and shows have to be true to the main idea that the author wrote. If the story is about consumerism, the visual content has to showcase it clearly and loudly. Books being made into movies usually become victims of misunderstanding and incorrect creative decisions. A lot of irrelevant material is added, which can have an adverse impact on the story.
And truth to be told, there have been a lot of books turned into movies and TV shows that aren’t on par with the original material. Since the internet is full of polarizing opinions (looking at you, Twitter), someone asked on AskReddit the question we are all eager to answer — “Which movie or TV adaptation is the biggest letdown for you?” Scroll down and upvote the answer you agree with the most.

#21 Artemis Fowl

"I loved the Eoin Colfer book series Artemis Fowl. I even had The Artemis Fowl Files and the comic remake from the first book, so I was very excited to see my favorite antihero main character in a movie adaptation. So yeah, let's not talk about the Artemis Fowl movie... I'll go re-read the books instead."

#22 Wheel Of Time

"I hate how dumbed down Moiraine was on the show. She was just running around reacting to things instead of the spymaster and strategist she was in the books. Book Moiraine knew things and her greatest strength was also her greatest flaw. She felt she had to control everything around herself. She's one of my favourite characters in the book and they turned her into a generic, armwavy magic lady.
Not to mention all of the set pieces that were changed or omitted that is going to change the end of the story. I get it's a different medium, but they didn't even try."

#23 Queen Of The Damned

"That was my first experience with a bad adaptation to a beloved book. I was so mad they left so much out - like I know it’s one movie and the book is stacked af, but don’t remove the entire history of how the vampires came to be to force in a romance that was never even hinted at in the book, sincee they interacted for mere seconds and without really talking. The soundtrack, and Aliyah, deserved better."

"The newest “All Quiet on the Western Front” completely missed the point even if it’s visually pretty cool."

#25 True Blood

"True Blood always comes to mind. I loved how it started. The first few seasons were mostly faithful, and even with the changes it was still good. But it started to go downhill in Season 4 with how they treated the witches storyline, and then from Season 5 and onwards it was completely unrecognizable from the books. I still mourn what it could have been because during the first few seasons, I considered it one of my top favorite shows."

"I’m so glad someone else was as disappointed I’m Ready Player One as I was! My husband didn’t get it so I made him listen to the audiobook. Just like why make so many changes, the book was so rich!"

#27 Tales From Earthsea

"I was coming here to see if anyone else had mentioned Earthsea. I have no words for how terrible the Syfy channel version was and then the Ghibli version...ugh. I wish it could get a proper adaptation."

#28 Under The Dome

"Under the Dome by Stephen King. It's not my favorite book by him by any means (wtf that ending), but I still enjoyed it and was interested in the tv series when it came out. Nonsensical changes, mediocre acting, the works. I didn't watch Season 2 and can't say I was at all surprised it was canceled."

#31 Cirque du Freak: The Vampire's Assistant

"It was one of my favorite series when I was younger. I get why they tried to combine three books into one movie. But it would have been better as a darker sort of Mini series."

#32 Misery

"Misery was overall a good movie and a great performance by Kathy Bates, but so much of the book was the protagonist’s internal monologue and the novel he was writing while being held hostage, and the movie couldn’t capture that."

#33 Watership Down

"Came here to say this too. I don’t understand why they have to rush through everything when there’s so much worth exploring. it had potential but just didn’t take its time building the world or the characters. I didn’t like the original adaptation either."

#34 The Lovely Bones

"I did not enjoy the film adaptation of The Lovely Bones. The book was so dark and sad, and it seemed like they wanted the movie to be aimed for a younger audience, perhaps? This is a difficult task for a story that starts out the way it does."

#35 The Time Traveler’s Wife

"The Time Traveler’s Wife. They took a dark, bittersweet story with two very complex characters and made it a boring, sappy romance. Family is a huge theme in the book, and that isn’t there at all in the movie. Loss and grief are huge in the book, not in the movie. And lots of references to punk culture and the Chicago of the '80s and '90s…not there in the movie."

#36 The Man In The High Castle

"In The Man in the High Castle, Philip K. Dick presented the most chilling alternate history of World War II where the Axis powers win. There's a deep but very understandable horror in how the novel does not hinge on any plucky freedom fighters, because overturning the new Nazi world order just isn't conceivable. Rather, the book is about desperate humanity under triumphant fascism and how that shapes what is and is not possible. The Amazon Prime series based on the book is about plucky freedom fighters overturning the new Nazi world order. It is absolute garbage for morons."

#37 The Seeker: The Dark Is Rising

"The Dark Is Rising by Susan Cooper. They turned it into a movie called The Seeker: The Dark Is Rising. Just blatant commercialization: Give it a catch phrase, make a franchise, and churn out lots of mindless crap. I was sad that Eccleston was in it."

#39 Legend Of The Guardians: The Owls Of Ga'hoole

"Legends of Ga'Hoole (based on Guardians of Ga'Hoole) they made a lot of pointless and unnecessary changes to the world, lore, and characters, which was even more baffling when they already bit off more than they could chew by deciding to cram the first 3 books into one film. Turning Otulissa into a soft spoken, shy, "girl next door" was especially heinous. The marketing too was absolute "genius". They made it look like a light-hearted kids film, completely going against the tone of the series, while the actual film was quite dark; true to the series tone, but scaring the crap out of the kids they tricked into coming to see it. It just showed they had zero faith in the source material and its own audience, in which case... why make a movie at all?"
