"Petrified Bubble"
I was really confused by the scene where they went outside, and saw the petrified matter on the ground, and then declared that time stopped within the bubble but continued outside of it.
I figured, after seeing that, that the ending of the movie would be realizing that while they were inside the loop, the war had concluded outside their time bubble. But I am left wondering what that scene was even for.. they deduced that time was going outside the bubble, but repeating for them within; and then they further found that they had repeated the day tons of times. Yet if time had continued outside the bubble, what about Sonny calling the troops in that were outside of it?
