If you're unfamiliar, Wiseman shoots a lot of location and institution based film. Unprepared, without narration, without seeking "spectacular" events. A lot of plain ol shit that happens in these places. Also, the platform it'll be hosted on it turns out, is pretty cool too - free with library card or university login.
"Frederick Wiseman's entire catalog, including current Oscar contender "Ex Libris," will be available for streaming on free service Kanopy."
