Season 1 of Unforgettable generally received mixed to mediocre reviews, with many critics finding it to be a standard procedural drama that fails to live up to its ambitious title . While the concept of a protagonist with a perfect memory (hyperthymesia) was seen as an interesting "hook," reviewers often felt it was underutilized or became a repetitive gimmick.
