Matt Singer’s review published on Letterboxd:
Normal Brain: Stallone went to Russia to make a piece of Cold War propaganda. At least 30 percent of the movie is training montages.
Galaxy Brain: Stallone went to Russia to make a tribute to the geniuses of Soviet montage. Rocky IV is at least 30 percent training montages because Rocky IV is the American Man With a Movie Camera, and Stallone is our Dziga Vertov.
