Skull Island is actually my favourite of the Monsterverse movies. It really redeemed Kong as a character for me.
I saw Weaver as more representative of the British and American women photojournalists that broke the most important stories of the mid 20th century.
Clare Hollingsworth from the UK broke the start of the Second World War. Other American women played a similar role in Vietnam and Cambodia.
It seemed a smart and authentic way to include a woman in the mission, other than as a Monarch scientist who already knew that there exist Titans.
Choosing a blonde actor for the role may visually connect to previous Kong films but it also is accurate to the women photojournalists she’s representing.
As a side note, the two Monarch scientists who survived live on to be the parents of a character who appears in one of the subsequent movies. The Randas aren’t the only multigenerational Monarch researchers it seems.
