Viola's work often exhibits a painterly quality, his use of ultra-slow motion video encouraging the viewer to sink into the image and connect deeply to the meanings contained within it. This quality makes his work perhaps unusually accessible within a contemporary art context. As a consequence, his work often receives mixed reviews from critics, some of whom have noted a tendency toward grandiosity and obviousness in some of his work. Yet it is this very ambitiousness, his striving toward meaning, and attempts to deal with the big themes of human life, that also make his work so clearly appreciated by other critics, his audiences and collectors.
