A great example of why a mawkish and specially political attitude toward directing always ruins movies. But this one is not even failure, it's bullshit.
One of the brilliant start to storytelling I've ever seen:
[Inside-Interroagation scene-Boy starts to confess]
"There's a fish that spends its life swimming to and fro. Fighting water that seeks to cast it upon dry land. Beacuse the water rejects it. The water doesn't want it. These long-suffering fish, so attached to the element that repels them, devote all their energy to remaining in place. You'll never find them in the central part of the river, but always near the banks."
[Match-cut to Zama while standing near the banks]
