It was not a good mystery. I thought it was way too simple to solve way before the movie was over. I'm also tired of movies where the police are painted in an unflattering light. The supporting cast did a good job. I do think, though, that the roles were very stereotypical. There wasn't anything fresh and new about this film. The worst problem was the serious miscasting of the lead role.
I totally agree with the earlier comment on Marlo Thomas not being a good choice for the role of a mother with a young child. She's still attractive, yes, but she does look much too old to be the mother of the little boy. She looks old enough to be the mother of the actress playing her sister. I could have enjoyed the film much more if that oddity hadn't kept bothering me.
The same applies for William Devane. Despite the fact that men can have children much, much later than women, I think they look silly.
