In these parlous times, there can never be enough criticism of bankers and tame politicians enjoying what Milton Friedman called socialism for the rich. Ashcroft's documentary lands some punches, but it is hampered by a PowerPoint-style presentation. As our western empire declines, he sees four apocalyptic horsemen: crooked finance, terrorism, poverty and ecological collapse. It's all fair comment, with sharp snippets from Noam Chomsky and the FT's Gillian Tett, although the tone is patronising sometimes. Ashcroft unveils some bold cures at the end, but we need more specifics.
