After the pilot aired, members of the Rocky Mountain Tribal Leaders Council, Coushatta Tribe of Louisiana, Global Indigenous Council, Great Plains Tribal Chairmen's Association, and the Union of British Columbia Indian Chiefs (UBCIC), among others, addressed a letter to ABC Entertainment President Karey Burke and series creator David E. Kelley, "accusing the show of “at best, cultural insensitivity, and at worst, appropriation” due to being set in area with a disproportionately high rate of Murdered and Missing Indigenous Women & Girls (MMIWG), yet not having any tribal representation in the show."
