Elderly with Alzheimer's Shouldn't Be Subjected To Horror Movie Suggestions on Home Screen

Roku often displays horror movies, violence, and other disturbing content suggestions on my Home screen. 

A family member has Alzheimer's and they get easily terrified. Why should they be terrified just by me turning on my TV set? 

I opted in to personalized ads to hopefully reduce the horror and gore suggestions, but it hasn't worked.

Roku, PLEASE allow us to OPT OUT of displaying disturbing content (murders, horror movies, violence, etc.) on our HOME SCREENS.
