Damon Houx reviewed Side by Side for Screen Crave. Overall, Mr. Houx thought the film was thorough in covering the subject matter and balanced in presenting both sides of the issue. With respect to the interviews, he thought they were great saying:
Hearing from someone like Anne V. Coates talk about editing Lawrence of Arabia is magic, and Reeves brings these people out.
The only negative the reviewer could come up with was it was for nerds and gave it a rating of 8.4/10.
