Side by Side first made it’s debut at the Berlinale back in February 2012. Here we are over a year later and it is still racking up reviews. The Birmingham Post has a reviewed the documentary and given it 5/5 stars. In addition to the typical highlights, the post makes mention of the film’s 15 rating due to the over use of the F-word as they politely put it.

Note: I went and checked by copy out of curiosity to see what the rating was state-side and didn’t see one. According to the information here, MPAA left the film unrated due to auteur profanity (side margin).
