I see first reply was any Stephen King book turned into a movie. True! Most anything really is better in book form, more detail. But I'd also say The Horse Whisperer

there is alot of books that are better than movies. most of them are in my opinion mainly because there is alot more detail involved.

if i have to choose tho two books ive read recently that were better than the movie would have to be Lone Survivor and Blow both books have way more detail than what the movie was able to portray. really good books

I would say the book Flowers in the Attic by V. C. Andrews was better than the movie. While most of the book was included in the movie, it didn't seem to jive. I've read the book a few times and it draws me into the story line every time. I was a kid the fist time I read it in two days. Now I can read it in a day. I;ve only watched the movie once and partially once.

Hands down one of the roughest book to screen transitions I've seen so far was the Shannara series.  There was so much IMPORTANT content left out it almost made me cry.  Whole characters that didn't even make the cut, and entire adventures that were just gone.  If it didn't get yanked off the air it might have improved but seeing it cut so short ruined the whole thing.
