With not much information about this documentary and the great idea of screening it in cinemas one night only around the globe, I expected something special or at least very juicy in terms of fan service. But... it's just a collection of clips during the Humanz tour and some very sparse and out of context insight on some tracks. They clearly wanted to give some use to a lot of moments they had recorded and decided to make a documentary out of it, but with no thread, no structure, not much attention put into pacing, not much input on the songwriting and actual music making, and a lot of typical behind the scenes recordings of "oh man, it's great making music with these guys, Gorillaz is my family"... yea, you can tell that the people who'll like this the most is precisely Albarn as his friends. It's like if I made a montage of my vacation, me and my buddies will love it, but even if you know me you'll have a hard time connecting with it if you weren't there.
I won't be too harsh on this since this was later uploaded to Youtube for free, but I was one of those who went to the cinema just for the idea of a Gorillaz movie and it's not the same to watch something like this while it's in the background in the comfort of your home, going for some snacks, chill out and so, than watching it in cinemas where you have to stay on your seat with no pause button and with the expectation of watching something more noteworthy... yea, it wasn't the best. Not a horrible experience by any means, and I'm sure people at home will be more ok with it, but my viewing experience was kinda lackluster.
