I do my best to avoid movies/shows based on books. The way the director/producers envisions it never stacks up to what I imagine and once I see it on the screen it's ruined cuz now that's what is imprinted in my head. 

GoT, The Last Kingdom, The Witcher, even classics like the Sharpe Books by Bernard Cornwell... none of it is as good as they should have been.

The Alex Rider teen spy series was one of my favourites as a kid! Both movie adaptions sucked complete ass, but recently Prime Video has released a TV show and I found it to be pretty good. I felt it really captured how much of an amateur he was and projected that aesthetic well!

The Crow

I love the movie and Brandon, nuff said!  James Obarr's writing is incredible in the comic book series which I have a 1st prints of :)  I think the Comicbooks are superior than the movies but cinematically, Brandon Lee introduced a style of film that made a huge impact at the time.    

Definitely, Time Travelers Wife! But the movie still the bomb :)

I Am Legend by Richard Matheson is by far better than any of the adaptations (The Last Man on Earth, Omega Man, and of course I Am Legend). The best adaptation is probably The Last Man on Earth.... The worst ending is definitely I Am Legend. 

The biggest one for me, was the Vampire Chronicles by Anne Rice. Whilst Interview with the Vampire was fairly close, Queen of the Damned missed alot of what made the book so good, one of the actual main characters to the plot infact. After reading the book, the story felt a hell of a lot more complete.

Although I seem to be one of the few that enjoyed the film Dragon was no where near as good as the books. But tbh it was a very lazy adaption, I mean the most obvious was the fact that Urgals where just men. Despite the fact it was incredibly influenced by Star Wars almost to the point of a carbon copy I really enjoyed the books & wish they'd done a better job then maybe they'd have gotten to make the whole series.

I know for a fact the chronicles of narnia is a much better book then the movies. Far more in depth and detailed.

I Am Legend. The movie is considered great by a lot of people however most haven't actually read the novel it's based on which is a shame because it's such a good read. The worst part for me is the ending particularly because the phrase "I am legend" has a much cooler reason behind it as opposed to the silly happy one from the movie. 

Going back to grade school books... But Indian in the Cupboard. Loved the book, but the movie not as much.

I went and read the Hunger Games recently as was intrigued to how much they had butchered it for the screen.  I was both shocked and amazed to discover that the films are pretty much a carbon copy of the books.  I don't think they really changed anything to be honest.

I would agree with you Madhatter in almost all cases. The exception to date though that I have found is - the book thief - pardon the pun. Great book bit dark but you know....didn't want to watch the film but they smashed it too. In tears with both.....
