What's the essence of igbo movie when one tongue can't be used?

I watched one igbo movie yesterday, 3 ladies, one was speaking deep owerri, d other was deep enugu abi nnsuka, the other weda na awka abi ahozara she dey rap?

I strongly believed dey dnt even understand demselves let more passing a clear message for viewers understand.

What d work of the director and producer? Abi na hausa man dey produce igbo movie?

Abi dem com tell us wia dem from? Lol.

Why not use this general igbo like the musicians uses or even slangs?

We just dey over do sef.

End of the day I no understand one tin

where did u watch it. cos I understand most Igbo movies if not all on African magic, BT it better for them to use central Igbo which is easily understandable, I know we all want to promote our verious Igbo dialect BT with central Igbo we can easily adapt to other verious Igbo dialect. it a gradual process, African magic Yoruba and Hausa didn't start today.
