I surprisingly liked The Eye because it was more about the life of a blind woman readjusting to the sighted world. There just happened to be some scary things in it. Whichever part of the movie appealed to you, the DVD has some deleted scenes that feed both needs.
DVD Review: The Eye
Scary omissions include hallways with bleeding eyes and other gross gags. Scary visions in the tradition of Asian horror are included.
Plot scenes include more adjustment to new vision and the ramifications on her relationships. There is another scene of Jessica Alba performing music and an actual eye therapy session.
If you thought the film was missing out in any one aspect, there's more here. None of the scenes tremendously build on what's already in the film, but there is more to enjoy.
