Catching the Black Widow

Watching this is rather confusing. The actors don't appear to be professional, and the script is all over the place, making it hard to understand why anyone depicted is doing what they're doing, despite its being based on actual events.

For a black widow she sure ain't that smart. Months after doing away with her latest victim, and his family all good and acceptable of how it was portrayed happened, why would she then supply his sister with all kinds of documented information concerning his death? It's done, all quiet on the western front, go work on your next victim..geez. Anyhoo, this is a made for TV movie, understandable..so might as well finish the damn thing and move one//
