Good, but could have easily been a mini-series with narration
The absence of narrator really added to the authenticity of the documentary (movie consists of a series of interviews mixed with raw footage). With that said, because of this some crucial topics only had a passing mention or not mentioned at all.
For example, automaidan and titushki had a huge role in the events that unfolded but it was not explained who they were and what they were doing, also the impact of social media and Internet is not mentioned at all. It would also help if the documentary went deeper into the persona of Yanukovich with subsequent opening of his luxurious residence to the public, which would help give a better insight into why the people were protesting (the movie makes it look like Maidan was a pro-EU protest, but a lot of people were there rather to protest against a corrupt system, of which Yanukovich was an embodiment).
The Sick Boy method?
[looking at Sick Boy passed out on the floor]: Well, it nearly worked for him
