Using Figma and a number of screen shots of Netflix, I put together an option for the finished feature.
At the end of the movie or show when closing credits are running the movie will minimize to show the user what is coming up next in the play list. The user is also asked if they like or dislike what they have just finished watching to allow Netflix to select “you might like this” content for that user in the future. I added an additional line to the minimized window simply asking the user if they would like to remove what they have finished watching from their watch list.
They can simply do nothing or say Yes. In this case “Yes” is presented in red, the same red that Netflix use for their logo to make it stand out as an actionable item.
I also thought of implementing a Hide function, since the user might be watching a series and may only want to hide it from their watch list until a new season is released, which would simply tidy the watch list up.
