Giving Psycho: Sanitarium a 4 1/2 star review and naming it a “Top Pick,” RT Book Reviews said:

“Taking his lead from Bloch’s original Psycho, Williamson devises an
amazing horror story that goes a few steps beyond the first. Unique in its conception, Sanitarium details gruesome life within the walls and deals with the varied personalities therein. Several unforeseen twists lead to the surprise ending.”
