It looks like the production team interviewed the guy running the shop and then displayed the video material to the people who had to deal with him professionally wise (police, psychologist, prison warden etc.) for comment. This gives the documentation a very consistent look and feel.

Recreating his bedroom that he used to run the store from is good for illustration and beats the regular documentary by using the real perpetrator.

The "drug lord" gives the impression of a charming and eloquent young man. The documentary though does not question, whether this guy might be a narcisist, who loves to present himself and they are giving him a platform to do just this.

I found it pretty entertaining and I couldn't resist chuckling because law enforcement was so annoyed about Max and at certain points even personally offended about his lack of remorse. Their demeanor and facial expressions were the best!

It's crazy to think what this person did but also for so long without being found out. Very interesting documentary.
