When I watch a movie, I use someone else's imagination. Everyone has a different perspective about something, and that's why we don't see things in the same way. When you read a book, you have your own feels, your own perspective and imagination, you read that book and then you think about what happened there. No one will help you figure out what's all about, it's a mistery. No clues, no signs. It's just you and your imagination. But, when you watch a movie, it's not all about you anymore. There's someone behind the scenes who made that movie based on his own imagination, and you just have to see it in his own way.
