I found this movie listed under two different titles: "An Imperfect Murder" and "The Private Life of a Modern Woman."
I'd like to suggest a couple more: "A Series of Insufferable Conversations," or "A Boring Murder." Wow, it's so bad. If you're looking for a thriller, this is not a thriller.
My takeaway from the movie was "huh, she had a nice apartment." I give it one super boring star.
