Nowadays, sententious is usually uncomplimentary, implying banality, oversimplification, and excessive moralizing.  The original Middle English sense of sententious was full of meaning, a meaning adopted from Latin sententiosus (from sententia, meaning sentence or maxim). In Modern English, sententious has sometimes referred to what is full of significance and expressed tersely.
