The book or the movie?

Which would you say was better?

As you know many incredible books that we all know and love have been made into movies. Harry Potter, Twilight, Willie Wonka an the Chocolate Factory ect.
They are all done very well and are highly enjoyable. But have you ever said to your self when watching them
"That scene wasn't how the book went."
Or at least something to that effect?
Or sometimes the movie changes it completely like the Walt Disney movies or the latest Alice In Wonderland. I'm not saying they were changed for the bad. They are very good but not like the book.
Or maybe after reading, we will say Twilight as an example, you got disappointed by a character or they missed out a funny scene in the movie. It could be disappointing for that Twi- hard fan.
Also with a book it's almost like your in it. You can make the scene look like what your imagination lest you. I think its maybe more close and personal in a way. That is if you are like me and really get sucked into the land of the book.

On the contrary movies might be more visually dynamic, in that the scene is there for you and it has the talented actors making their character as like the book and life like ( as they can .) And these days you have all the special effects and 3D ect. People could say there isn't anything that you can get from a book that you can't get from a TV faster. (not sure i agree with that.)
And I don't know about you but when i read a book that's been made as a film, i can't get the film out my head as i read, which may not be a good thing because then you have you expectations set out for you and you can't let you imagination run free.
Also i think it's a little sad when someone says someone LOVE what ever film but doesn't even know it's a book first
Another thing i don't like is when a book is made into a movie and then made a book again but as the film, i don't know why but i really hate that.

So as much as i adore movies, books will always be the love of my life.

What do you think?
