Metacritic reviews

Considerably less slick than "An Inconvenient Truth," and no less urgent.

The one film to see on this most crucial subject.

Ultimately a triumph of redemptive ideas that DiCaprio ­-- God bless his celebrity -- may finally succeed in transporting from the environmental fringe to the mainstream moviegoing audience.

Thankfully for audiences, 11th Hour is not without hope. The filmmakers save the most exhilarating portion for last when they ask what's being done about the problems.

It isn’t much of a movie (unless your aesthetic was formed in high-school science class), but it will be hugely informative to aliens who land on this planet in a thousand years and wonder why there’s no welcoming committee.

Presents the viewer with reams of depressing data, loads of hand-wringing about the woeful state of humanity and, finally, some altogether fascinating ideas about how to go about solving the climate crisis.

Arguably a more important movie, which more clearly lays out what must be done to save the world, and how we can begin.

This activist documentary -- alternately impassioned, despairing, edifying, and hectoring about all the ways humans are screwing up the earth in a death rattle of hubris -- shouts, People, do something! In contrast, "An Inconvenient Truth" feels positively hushed.

The 11th Hour is a bit like "An Inconvenient Truth" at Woodstock: a little spacey, a little preoccupied with self-love and prone to the occasional freakout.

A cautionary eco-doc so earnest and moth-eaten it should properly be seen on filmstrip during fourth-period social studies.
