I'll give high kudos to the performances in this movie, especially Rachel Alig, who totally disappears inside the deranged and nearly sympathetic character of Shelly. However, I felt that some of the sadism exhibited by Shelly was seemingly without motivation, which would have help and left a significant hole wo fill in. And the ending seemed as if the producer ran out of money before the film could be finished, offering no resolution and nothing satisfying to take away from the journey we were on. THE CLEANING LADY could have been a cut above the familiar psycho-friend subgenre but in the end squanders the opportunity given it .
