Chief film critic, Mark Adams, wrote a detailed review of Side by Side for Screen Daily. After covering some of the films major points, Mr. Adams ends with:
It is a fascinating story – especially for those in the business – though to a degree there is an awful lot of history, information and opinion to pack into a modest running time. But in the end, Side By Side makes for compulsive viewing…and you learn to love Keanu’s laidback interviewing technique which helps pull aside the technical terms and focus on the beauty of the final image.
