It was a pretty good movie.
The story has many different variations, and the ending depends on what you decide. The neat thing is that you can then go back and run through several others before ending at the credits.
The only downside of this is that because there is so many variants, you do not really get a clear answer as to what exactly is happening, because once again, you decide what happens. What conspiracy is occurring.
There's quite a lot of references to other Black Mirror episodes, which are fun to pick up.
As trippie as it was, it was a fun one.
