Leigh Whannell freshen and updates the classic horror character, the invisible man, in this movie. He proves that he has both writing and directing chops with this movie. His efforts are greatly enhances by Elisabeth Moss' acting. She does amazing in this movie. The story is simple, a woman is terrorized by an invisible person. It is so simple, but simple stories do not always equate to good movies. However, "The Invisible Man" adds depth to the story and makes this horror movie an all round good movie. Moss' character, Cecilia, is in an abusive and manipulative relationship with Adrian who is a powerhouse in the optics industry. She runs away and hides at a friend's house. She is too scared to leave the house due to not wanting to be seen by Adrian. News comes that he is dead and that she has been awarded a large sum of money in his will. Things seem to be going great until strange things begin happening. Her life gets turned upside down and she knows it's Adrian, but she can't see him! Nobody believes her, and they think she is crazy. Things keep happening that place her in a position to be thrown in a mental institution. Things proceed from there, but I do not want to get into spoiler territory. Moss plays her role perfectly. She has to act as if she is sane, but at the same time be slightly convincing that she is insane. She does great. The pacing of the movie is perfect. It is slow enough that we can get the full development of Cecilia's tortured persona, but quick enough to keep us on the edge of our seats. It is not a "scary" movie, but it is thrilling and suspenseful. As for R-rated movies, this is a fairly soft-R. The language is not too rough, and there is a bit of blood. They could have made this PG-13 really easy and appealed to a wider audience. Overall, I give this movie an 8/10.
