Because reading the book we can imagine the story in the book. Imagination about the characters in the book. If we read the making TV series or movies. We know.Because in a play or film often excerpted the books out for a limited time and budget to build for me, and reading a book like that. Can make us feel like ourselves in that situation.But watching TV. We can't comfort of imagination that, for example, the book "Sherlock Holmes." I feel that the puzzles in the book. How to explain the author. Can make me to think about how to solve the puzzle as possible.. because there are some certain range crossing the content when you leave. The details in the film incomplete, like a book I read.
