I am ever so grateful to you, Amazon Prime Video, for adding this show to your streaming services. This show was and still is the background to my young adult years. However, I am sorely disappointed that you have chosen to not offer ALL the seasons as Season 4 is blatantly missing. As a faithful Prime member for the longest time, I should have access to all the seasons of A Different World just like any other TV show you would offer for streaming purposes. I am hopeful that you will see this grave error as one that should be rectified immediately as to keep those faithful Prime members, such as myself, highly satisfied with all of their Prime benefits that you offer and who will continue to tell their friends and family to give Prime membership a serious thought because of how happy they have been with Amazon's many offerings in good deals and quality TV/Movie streaming services. In closing, please add Season 4 to complete the entire seasons of A Different World. It would be greatly appreciated by so many. Thank you.
