Have you ever wanted to see a book that you enjoyed made into a Manga? Do you think it would help to have some of the plot translated into visual images? (Aside from a movie, etc)

How about a Manga that you think would have been better if it had been a full novel?

Have you read any Manga, that had a fantastic plot, and you want to tell other's to read? How about some terrible ones, where not even the images helped to progress the story?
