I did enjoy 'How to Blow Up a Pipeline', but I couldn't help but want to rewatch 'The East' (dir Batmanglij, 2013), which had a similar structure (re denouement), but the stakes seemed higher in 'The East', and the psychology of the characters were a lot more deep and varied. I think that was because you come at 'The East' from the point of view of an outsider, and you watch her character arc alongside that of the eco-terrorists, and see how interacting with them changes her (and changes you, as a viewer, too).
But, even so, I'm very glad I did watch 'How to Blow Up a Pipeline', and the film made me want to read the source material.
