Movies. They're faster, visuals can be breathtakingly stunning, seeing and hearing an actors subtle expression changes, voice cracking, it's more involving. I've cried from sad books once or twice, but it's one thing to read something sad and another to experience he empathy of watching and hearing a character go through an emotional scene. Even non emotional scenes. I've teared up just from being in awe of a powerful scene. Sometimes just the music makes me cry tears of happiness. I can't get that from a book. I also just love seeing effects and moods in movies. A tim burton stop motion movie would probably translate horribly into a book lol
Books because of more detail but movies because of the easier visualization
Well in general I prefer books, they have more details and more room for imagination. But a movie only takes a few hours to watch and you can actually see the characters one to life on screen. So there's things I like about both...
