I don't expect writers to know highly technical details. But a golfer holding a driver on the green? No, never a driver. That's pretty basic. It is very hard to believe that no one on this movie would suggest the obvious choice of a putter instead. Admittedly, this is a minor detail that has little impact on the movie as a whole.
In this movie, Sam doesn't really begin solving the case until over half way through. Until then, her role is to fumble through trying to take care of a baby by herself. Also, it is pretty obvious who the bad guys are and who the innocent bystanders are, with one exception. There is one mystery player that is revealed toward the end. Other than that, the story pretty much wanders around toward a predictable conclusion.
The acting is borderline. Nina Siemaszko is an insult to strong capable women. She plays the ADA, Cassie, who is basically Sam's spineless stooge. It also bothers me sometimes how loosely Cassie plays with the law and legal procedures. Many of the other characters are one dimensional and exaggerated. Kellie Martin is appealing especially if you follow the series although her acting isn't great either. She always has some witty dialogue especially with Philby.
Out of the amateur detective series currently running on Hallmark Movies and Mysteries, I place this series near the bottom and only above the Aurora Teagarden series for the worst slot.
