Why were puritan separists unhappy with the religious structure of the angilican church in England?

Puritan Separatists were unhappy with the Anglican Church because they believed it retained too many elements of Catholicism and was insufficiently reformed. They sought a more pure and simplified form of worship and church governance, emphasizing individual faith and a direct relationship with God. The hierarchical structure and rituals of the Anglican Church conflicted with their desire for a congregational model that allowed for greater local autonomy and spiritual integrity. This dissatisfaction ultimately led them to seek refuge in America, where they could establish communities based on their beliefs.
