Critic Reviews

If “Planet B” is less than a sum of its parts, ending before the Webb is launched, and lacking overall closure, it’s still a wonderfully observational portrait of exploration.

Humbling, awe-inspiring and frequently head-scratching, like a solar system mobile, Kahn’s film has a bewildering number of moving pieces.

The Hunt for Planet B delivers a captivating viewing experience, showing the sometimes-thin line between science fiction and the true scientific future.

It manages to put a friendly, mostly female face to all the technical exploits and celestial theorizing, underlining how much the desire to uncover the secrets of the known universe is something that's all-too human.

Above all, the movie makes a case for the tremendous resources on display by attaching them to genuine investment in the stakes at hand. When the telescope gets to work, it may not deliver firm answers for a world that demands instant gratification. But it will provide many reasons to keep looking up, and The Hunt for Planet B captures many of them.

The Hunt for Planet B is an evocative documentary.
