Most episodes of "Black Mirror" are a little disturbing, and “White Bear” is no exception. At first, it seems like a dystopia or post-apocalyptic world. After some reflection, I think what is often the most unsettling thing about the “White Bear” episode and so many other episodes of "Black Mirror" is you are kind of going through the experience with the character.
"Black Mirror's" "White Bear" episode was certainly one of the darker episodes of the series. I watched it late at night, and it left me feeling unsettled until I fell asleep. I think the episode really reflects hyperbolized, but possible, versions of our society.
