Ibolya Fekete narrate her story, allowing movie watcher to determine who is write and who is wrong. And this is not an easy decision... it's not like a primitive story about straight and heroic American soldiers (Hurt Locker).
Also, people in 'Chico' knows what they are fighting for. They may be wrong and they are cruel, but the are not like Americans brought to Iraq by obscure political reasons of W.W...
The more you see 'Chico' the more you start to empathize to its main hero... and you're becoming devastated together with him.
I suspect, though, that it would be harder to understand this movie for people who were not born in USSR or other communist country, who didn't hear their propaganda for years.
