Critical response
The season was met with generally positive reviews from critics. R. L. Shaffer of IGN rated the season eight out of ten, signifying a "great" season. Shaffer stated that although it was not "particularly refreshing," the season was "damn good, with great cinematography, solid performances and slick, stylized action and drama." Dave Trumbore of Collider stated "The new Five-O plays like an action-packed combination of The A-Team's antics with the realism of The Shield. Though season one doesn't choose to go nearly as dark as many episodes of The Shield did, Alex O'Loughlin brings his physical presence and stunt training from that series into Five-O." Trumbore was also receptive towards the action sequences, which he felt was "one main sell of the show." Stuart Galbraith of DVD Talk had "many criticisms" with the season, but liked some aspects of the show because "clearly there's an attempt to draw from the best elements of the original series."
