Deserved at least one more season, but...
...perhaps this show was too heavy? It was never visually graphic yet some of the details and things left to the imagination were a bit chilling. And this is coming from someone who regularly watches horror movies with far more explicit content. Not to mention none of the characters were exactly ones you would root for, except maybe Adam, but he was hardly on screen other than as a flashback or a "ghost."
The Family had a lot of twists and turns, which made it enjoyable for me. Same can be said for fellow ABC show Secrets and Lies (I like S&L, but how did that get renewed???). Yet I found the acting a bit more convincing in The Family. The finale was particularly good if there had been a renewal. As a standalone, it was frustrating as it completely curveballed you with the surprising ~comeback~ of Adam. Would have loved to see how they would handle his return and the fate of Ben, who I found sympathetic at times even if he was truly messed up (for obvious reasons).
Sad to see this sleeper mystery go. It wasn't the best written, but it knew how to keep me watching.
ABC is so weird with its renewals and cancellations this season so I shouldn't be surprised.
