In her review Frederica Mathewes-Green actually gave him kudos:
When Rachel and her dad argue over her need to have privacy for a roadside potty break, and his need to have her never out of his sight, we know that’s just the kind of thing that would happen. When they encounter people along the way who are kind, or who are suddenly and alarmingly vicious, or who are something strangely in-between (a great performance by Tim Robbins), we know we would meet that range of characters too.
