I do not rate this movie because I didn't watch it all. I gave up when Ali started going rogue.
I have a personal categorization of these amateur detective mysteries (called Signature Mysteries on HMM) based on how much the non-cop in the story violates procedure and even laws. As a result, I put the Gourmet Detective series in the positive category because the amateur is actually helping the police at their request and he rarely does anything his cop partner wouldn't approve. The different franchises are all over the scale with Aurora Teagarden being near the other end of the scale. This new franchise appears to be on the negative end. One of the first things Ali did regarding the murder was gather DNA evidence from a potential suspect without his knowledge. And she was interrogating people in ways which could potentially prejudice the investigation.
What little I did see wasn't positive.
Put this series on my no list.
