4 types of film openings and my favourite title sequence

These are the 4 types of film openings 

4 main categories of film openings.

My favourite title sequence is for Boyz N The Hood because it gives you an outline of the film itself and the environment of South Central Los Angeles which is full of gang members. 

This a screenshot of the local kids going to school.

He was told to teach the class by the teacher for being a class clown but when he got up there he had a lot of good things to say, he teacher wasnt expecting it at all.
He ended up fighting a class mate whilst teaching which lead to him getting sent home.

Him walking by the local gang members.

Seeing his dad as his mum told him misbehave one more time and you will go and live with your dad.
