VERDICT

Definitely not conventional in its approach. It does not really follow the 3 act structure exactly. There is not really a final act.

It follows the Beat Sheet for some of the way but gets lost after the midpoint.

This helps the nihilistic feel of the movie but perhaps makes it a little unsatisfactory.
