The theme of this movie is very heavy so the tone throughout the movie is obviously serious and dark. The first 30 minutes is slow but once the flashback started, it got serious so fast.

The whole flashback scene was so heavy and devastating and for some would be too much to bear. Personally, I had to pause several times because the scenes is very detailed and the acting was very convincing. It is also very eye-opening as this part of history. This will leave you in tears so if you planning to watch this, mentally and physically prepare yourself.

p/s: Do stick until the ending credits.
