Yup. A big yawn. It seems like it ought to deep and insightful, but is, as you say, "basically a story about conman/drug guy interwoven with biographical information and anecdotes about how this impacted his family". There's no connection between the two parts that goes deeper that "they knew each other once, but did they really know each other?". It'd be Hallmark, but the parents aren't sympathetic enough.
