I'd like to see the next release add post play as a selectable settings option.
I personally would like it and would make a safe assumption some would like to turn it off on settings.
The auto play feature is an option in the settings on Netflix.com. To disable Post-Play's autoplay feature on a Netflix profile, navigate to Your Account, click Playback Settings, then uncheck the option to Play next episode automatically. Other Post-Play features will still be enabled -- this setting simply turns off automatic playback of the next episode.
