Overall, this was interesting and the students were very sympathetic and remarkably mature. While I don't regret watching all six of the 45 minute episodes, I was left with quite a few questions.
Why did we have to wait until the 4th episode to get any real detail of the new principal's approach to turning around the school?
Since this was titled "Segregated America" (at least when shown on the BBC in the UK), how does it compare (e.g. funding, outcomes) to predominantly white schools? (In the 5th episode, we finally find out that there's a white school which is private, while this predominantly black school is publicly funded.)
What job prospects do the students have?
What happened to the students who were expelled (e.g. for fighting)? (We almost get to follow one student who is expelled and is sent to the "alternate school", but we don't get to compare "Hell" against "Purgatory".)
Why did the principal question the students' behaviour during Lip Sync Battle? Wouldn't you expect something like that to get a little rowdy and out of hand?
What's the rate of teenage pregnancy?
Is religion something that helps the general community (e.g. provides cohesion) or does it hinder (e.g. encourages acceptance of the status quo)?
In summary, I wanted (and felt I needed) to know more about the social context.
