Movieman630’s review published on Letterboxd:
Another Round shows the benefits of telling a relatively simple story with a deft directorial hand. The plotline of the film, which involves four high school teachers attempting to be constantly drunk in order to see if it will improve their lives, never overcomplicates itself. Instead, director Thomas Vinterberg simply sets it up, then uses it to examine the lives and regrets of these four men.
Of course, it doesn't hurt that one of these men is played by Mads Mikkelsen. He imbues Martin, the primary focal character, with the sort of repressed yet constant pain that may explain why a character would undertake such an experiment.
Vinterberg wisely never lets the film become preachy. He is not telling a cautionary tale about drug use, but rather using the drinking pact in order to examine people who have lost sight of their lives and goals, and don't see a path to reclaim them. The subtlety and performances are powerful, and are their own justification for seeing this film.
