Yeah, I didn't like it at all. Black Mirror is great because of the tight writing, extremely focused plotting and editing. This format just wrecks it (and yeah, you have to make many wrong choices to "get it"...which is still what wrecks this project). It's almost as bad as the actual choose your own adventure books. There's a reason that format failed--they were utter shit.
I'm guessing this will fail too, just like 3D. Humans just have too short memories or simply no appreciation of why bad ideas fail, despite how many times you try it again, just because "it just wasn't done right the first/last dozen time(s)!" We don't need interactive TV content. We just don't. Do your job, and write a cohesive story. It's your job to edit out the crap and piece together something solid out of a bunch of junk. Stop trying to convince the audience that they want to do your work for you. They "think" they do, but they will inevitably be bored by it or just hate it. It always happens.
