Movie is based on The Invisible man novel written by Herber George wells which is one my favorite. The movie takes the novels plot and adds some modern characteristics like problems related to modern relationship. Starting was dramatic which showed that this film is going to be a big psychological roller coaster for the viewers. Elisabeth Moss did her job perfectly as Cecilia. At a point I got sympathy for her in the film. The character of Adrian was also matching to the novel protagonist Griffin. There were some flaws though like why he was so obsessed with Cecilia even he has all the things in his life. I guess it may be because the director wants to focus on domestic problems of couples. I don't understand how Cecilia got tricked about Adrian's death by Tom so easily. By the way I think because Tom's full name was Tom Griffin so he may be the real invisible man and Adriana was just using him to haunt Cecilia. James was a supportive character exactly like Mrs Hall in the novel and his daughter may be the novel equivalent of Mr Hall . The character of Emily was pretty straight forward so I have not too much to tell about her. I like when someone says 'Surprise'that gave me the vibes that something planned is just completed and something fishy is going to happen. The Film gave me the vibes of psychological horror in perfect time duration but some small flaws just confused me till the end but it can be manageable.
