For our inaugural vote, we have..
Church Fight (Kingsman: The Secret Service)
Alma's Discovery (Brokeback Mountain)
The Case for Church Fight:
Sometimes a movie shocks you with violence, and sometimes it does it with an amazingly choreographed fight scene. Kingsman combines the two for a brutal moment in a church where the villain causes everyone to go into a rage and start attacking each other. Highly trained Kingsman Harry Hart is also there and adds to the carnage.
The Case for Alma's Discovery:
Brokeback Mountain is filled with several quiet, seminal scenes. While "I wish I knew how to quit you" became the film's most iconic, the scene where Alma discover her husband's secret is a powerful moment. Her slow walk away from the door into the kitchen is acting perfection, heartbreaking and terrifying at the same time.
