Film Recommendation

I love horror films. So I recommend one horror film called Mirrors to you.
It's about one man. He killed his friend, so he was fired. He found a job in a damaged building. There's almost nothing left, but mirrors were all around the building. Man saw many strange things in mirrors. Mirrors killed his sister. Man looked for somebody called Essecker. He found Anna Essecker in Monastery where mirrors were prohibited. At the end of the film devil returned for Anna. Man killed him but he  stayed in the mirrors.

I like this film because it is a horror and detective film.
