Okay yeah, they're definitely presenting Tzarist Russia as some shiny wonderland, which was... absolutely not in any way accurate, Pogroms (massacres) against Jewish people were common, the Tzars managed to get a bunch of people trampled to death at a poorly organized coronation, launched an ill-fated war on Japan that killed a shit-ton of Russians for no reason, the peasants were Serfs, little more than feudal slaves, Russia was failing to modernise socially, politically, economically or technologically, and many many other massive problems.
The Bolshevik revolution may have led to a shitty new state of affairs, but there's a lot of good reasons a revolution happened in the first place.
