Im a big Emma Stone fan I've seen all of her movies. Her acting in this movie was very good, considering how hard it would be to play that part. Being an infant in an adult body, her performance was spot on. Mark Ruffalo and William Dafoe gave great performances as well. I would have liked the movie more if there was less nudity. I wouldn't be surprised if the first cut of this movie was rated X. Parents forewarned.
