Under very tight budgetary constraints, Shimizu's films garnered much acclaim from both critics and genre fans for their effective use of limited locations and eerie atmosphere to generate chills. Shimizu was at the same time perfectly willing to show his ghosts onscreen, in contrast to some directors who might choose only to hint at their appearance. But critics noted that Shimizu's minimalist approach to directing and storytelling—a necessary by-product of the production's limited overall resources—allows the films to retain their ability to unnerve viewers. Very few scenes in the movies are graphically bloody, making such scenes more disturbing when they occur.
