The casting was bad to begin with.
The editors and producers did an awful job by not bringing life to the characters throughout.
The writer on the other hand did an amazing job. The premise of the movie is around relationships completely reliant on external affirmation ( the test) as opposed to the traditional emotional and physical attraction.
It kinda touches on the current modern society’s way of living I.e social media being a basis of approval.
Basically, people strive for social media approval of their relationships before cementing them.
My point: great writing, poor casting and production!
