What I like about this episode is its commentary on how rebellion can itself be commercialized and made a part of the system it claims to oppose.

I have a fan theory that the world of 15 Million Merits is actually a post scarcity society. Obviously powering the world with people on bicycles would be horribly inefficient and could never be enough generate the power needed to keep the world running. In reality it's all just to keep people occupied and docile.

I've written in depth reviews of the first four episodes of Season 4 and I'm planning to write the remaining two soon.
