Critic Reviews

The obvious political agenda behind Before the Flood may turn off those who still maintain that climate change is a myth, but the evidence presented in the film should at least cause open-minded viewers to rethink their position on the issue.

One of the most interesting things when watching Before The Flood is noting how the tone has changed in reference to climate change in just a decade.

It should all resemble a vanity project except for one thing: The film lays out the case for reform with steadfast rigor.

A sober, thoughtful documentary that combines a lament for a lost Eden with a rousing call to action.

Before the Flood is neither dull screed nor stat-heavy pamphlet, thanks largely to the questing intensity of its marquee guide.

Handsomely shot and entertainingly paced, “Before the Flood” may not tackle too much new ground, but given the sincerity of its message, its ability to assemble such a watchable and comprehensive account gives it an undeniable urgency.

While those of us who've seen dozens of similar docs could name plenty that taught or moved or enraged us more, Flood's filmmakers are intelligent in their use of the biggest asset they have: Not only do they keep their movie star onscreen, they work hard to tie viewers' concern for the environment up with his biography.

It's far more convincing — and enraging — when focused on the lives of real people. In these heartbreaking moments, Before the Flood grows more aggressive in its imagery and argumentation, becoming the climate-change documentary Americans need to see.

The documentary's focus on elite solutionism effectively erases the role of popular agitation in formulating social change.

The film wants to spur individual changes in behavior, but there’s a fair amount in it that might discourage you from even trying.
