I agree choosing your own ending would be a big mistake for most shows including Black Mirror. Like I said, I can't remember where I heard this but I was hoping the kind of 'interaction' that Charlie Brooker would introduce would be less explicit (i.e. you choose an option on the screen) and more implicit (e.g. you watch the show for a second time). If it was done in the right way, I think it could enhance the experience.
