Harriet Ryan and Adam Tschorn of the Los Angeles Times described the reality series as a: "Hollywood version of The Brady Bunch -- the harmless high jinks of a loving blended family against a backdrop of wealth and famous connections".Kim Kardashian described the beginning of filming the show, "When we first started [the show], we came together as a family and said, 'If we're going to do this reality show, we're going to be 100 percent who we really are.'"."These shows are a 30-minute commercial," Khloé Kardashian admitted in 2011, in response to a suggestion that the television series is used to promote their retail stores and endorsement deals.The reality series revolves around the children of Kris Jenner, and originally focused mainly on the children from her first marriage to deceased attorney Robert Kardashian: Kourtney, Kim, Khloé, and Rob.
It also features their parents Kris and Caitlyn Jenner (previously known as Bruce Jenner), and brother Rob Kardashian.
Kris' children Kendall and Kylie from her subsequent marriage to American athlete Bruce (later Caitlyn) Jenner have also been featured on the show since its beginning, along with Jenner's son Brody from another marriage, although he appeared very few times during the early seasons, mostly being called by his step-brother Rob to babysit their half-sisters Kylie and Kendall.
Cast members also include numerous friends and other acquaintances of the family members, most notably Malika Haqq and Jonathan Cheban who joined Keeping Up with the Kardashians in the second and third seasons, respectively.
It is often criticized for the high degree of emphasis on the "famous for being famous" concept, and for appearing to fabricate some aspects of its storylines.
Several critics also noted the show's lack of intelligence, and described the family as "self-absorbed" and "desperate" for fame.
