Pretty strong film.
A lot of things can be said about this. And a few questions could be asked too. But cutting to the core:
If it is a film to make me scared of muslims - it fails. Although I suppose it is great anti-muslim propaganda if you like.
If it is a film to make me afraid of how hate, fear and dehumanization can saturate a whole generation it works only too well.
This film could also have included various youth activities of communist regimes, some african guerilla groups and probably extremist groups alot closer to ourselves if you just twist the purpose slightly.
It is terrible to see those young children getting messed up for life (death). The best remedy I can think of is not to do the same thing myself.
