For both beginners and long-time aficionados, Future Shock! is a serviceable account of 2000AD's influence -- and how it altered the future of modern comics.

While the 2000AD British "brotherhood" put staid American efforts such as Superman in the shade, this film is mostly a series of middle-aged talking heads nostalgically discussing a past that we barely glimpse.

Everything from the post-apocalyptic ballyhoo of Mad Max: Fury Road to the Fallout video game series owe its gleefully violent tone a debt. But 2000AD did it originally with bold, brutal style.

Highly entertaining, hugely informative, but occasionally repetitive.
