Severely in example sentence
The characters are all severely lacking in charisma, particularly the so-wet-you-almost-don't-feel-sorry-for-him cat, the animation is lumbering and predictable, the musical number is flat and the story doesn't build naturally, instead resorting to a tacked on and completely unsatisfying finale in which the cat does a too-sudden about face and metes out a workmanlike beating to each individual rat, a production line revenge that is less than thrilling to watch.
