Not outstanding, but far from the worst of its kind. It's true that the "shock" ending is cliched, and most of the plot developments are predictable, but the film gets a great big boost from Gary Busey's three-dimensional character and intense performance. In some ways, "Hider in the House" is quite similar to "The Stepfather", another film in which a mentally unbalanced man wants to create the "perfect family", and although it has a much lower reputation, it is actually better.
