Herzog goes to Japan to make a film about a company that hires out actors, who become hired friends and/or family members for a day. It's not really a novel concept, but Herzog's documentary-style offers a new approach and the fact that the lead actor is also doing this job in real life adds a little intrigue.
Sadly the film itself is quite poor. Herzog feels lost in Japan and apart from some template shots (like Shibuya Crossing) ends up giving off a very touristy vibe. The film looks quite ugly, the music is ill-fitting and because of the form I expected Herzog's voice to pop up and give commentary on the story.
The performances are quite poor too and the fragmented setup doesn't really add much. It's a failed experiment that might've worked better as an actual documentary rather than a feature film. It's weird that Herzog didn't see this himself, as he's quite fond of making documentaries. Not good at all.
