Anyone who grew up in Britain in the '70s and '80s will be aware of 2000AD the comic. This documentary does a great job in reminding you how big is was back then.
To condense it greatly, it can be summarised as "Fuck the Tories, let's get pissed and try and get kids to think about the world."
If you ask me, that's a life well spent.
There is, thankfully, much more detail to the story than that, and it's told in a very entertaining way. There's some genuine LOL moments, some naked display of ego, shameful admission of sexism in comics, and a fantastic final line.
If you like comics, UK history or looking at strange people who draw pictures for a living, this is definitely worth a go.
