This is an interactive documentary but don't assume that means gimmicky and clicky and aimed at people with short attention spans. This is a significant, thoughtful and richly rewarding piece of work that explores the industrialisation of prisons in the US.
You begin by arriving in Canon City, Colorado, a town with 13 prisons. You check into a motel. It feels very game-like as you choose whether to visit your first prison, drive further into town or attend the funeral of prison guard who died on the job. But when you do choose, you are presented with engrossing insights and interviews, all superbly filmed. It's a grim world you've entered but it is almost hypnotically compelling.
One of the best things I've seen (played? experienced?) in years.
