Watched 20th Century Fox's 2008 Mirrors (1:51:05). It's the usual, Hollywood horror story formula in which the protagonist and his family are challenged by a life-threatening force, the protagonist hunts for an antidote, the conflict leads to a spectacular climax, and the downbeat ending shows us that evil is not completely vanquished. Not quite a B movie because of a well-thought-out production design and special effects.

Ben Carson, a rehabilitated alcoholic separated from his wife and kids (yes, the stereotype protagonist) must take on a job as night security in the multi-story ruins of New York's Mayflower Department Store, which was devastated by a fire in which many died. During his rounds of the ruins he discovers that the mirrors inside the store reflect strange images, images that already caused the deaths of at least two men, and now, his sister. Very soon his wife and kids are also threatened by images in mirrors. 

Ben discovers that the site of the Mayflower was formerly a hospital, its psychiatric ward being in the basement. The mirrors instruct him to bring them Anna Esseker, a former schizophrenic patient who was 12 years old and treated with a program involving mirrors in 1952. Ben tracks down Anna Esseker to Saint Augustine Apostolic Monastery, where she is now a nun in recluse. He takes her with him to the basement of the ruins in New York.

I'd rate this movie a good screening because it was entertaining and at least did not depend on a ridiculous screenplay, but I wouldn't watch it again, and neither was my interest piqued enough to watch its sequel.
