While I thoroughly enjoyed this film (for several reasons previously mentioned), I think it is important to clear up a one thing that has been repeatedly mistaken in these user comments.
This was NOT produced under Lenin's Soviet Regime, but rather shortly after Stalin took over in 1928. The government, then, disapproved of Vertov's film style, not seeing the proletariat message but rather only the formalistic errors that they saw as inherent. After passing directives to forbid formalist methods of production (most likely specifically for Eisenstein and Vertov), Vertov moved to Kiev to produce this film, where I apparently the government was less strict.
