‘Tehran Taboo’ is a spellbinding animated journey into the underbelly of Iranian society where nothing is what it seems from the outside. It would pay US media to watch films like Soozandeh’s once in a while. In fact, it would pay us all to do so, since we could walk away enriched by its wisdom. But the filmmaker’s genius here lies not in preaching, rather in thoroughly entertaining us, from the delicious rotoscope animation to the powerful use of characters that jump off the screen and into our conscience.
