It's obvious the people who watch this documentary are mostly blinks, but it really opens up to a wide audience. The documentary isn't about them flexing their achievements but it's more on the emotional side, and not boring at all.

If you're a hard-core blink you'd probably know most of these stuff but there are many things you haven't seen, such as their trainee life or Jisoo talking about burning the dorm.
For casual blinks/listeners, this documentary really lets you know more about BLACKPINK and dives a lot into their personality, you'll see their journey as kids all the way until now.
And people who've heard about Kpop and BLACKPINK, I would really recommend watching this because it'll be an entertaining experience.

And also because BLACKPINK is just amazing queens how can you not love them.
