I watched this movie again tonight and saw some things that I didn't see before like:
1. Sculpture with children dancing in circle and then appearance of Hat Man.
2. God is in the rain (possible "water" reference)
3. Girl shaving head (Brittney?)
4. The mention of milk
5. Showing the hyp. needle
6. The masked crowd of citizens w/o weapons at the end
Not to mention the message of standing up to the Govt and their lies.
This really blew me away!
