As a huge proportion of horror films become ever more identikit, gory and bland, it’s very easy to write off the whole genre as worthless. But we’re standing up and saying NO MORE! There’s gold in them thar pans of muddy shite, and we’re going to find it.

It’s nice when documentary filmmakers come up with new angles to the ‘poor underdog’ theme. Since the genre first became commercial enough for cinema release, we’ve had our heartstrings pulled every which way, to the point where the concept’s getting old. But Joe Berlinger’s new release Crude, which centres around a class action by a group of Ecuadorian tribes against a US oil giant, manages to raise some unusually interesting points about the nature of the environmentalist movement and just who is right and wrong in a case like this.
