A fascinating portrait of a modern artist and activist trying to make a difference within China's repressive political system. full review

The film's recurring theme is of an artist on a perpetual hunt for transparency, in his country and abroad. full review

A movie that somehow mixes apprehension for Ai with a feeling of warmth and, certainly, fun. full review

Affable and unpretentious, Ai comes across as a cagey operator whose candor is very appealing. full review

It's likely to change the way you think about art and politics and the state of China today. full review

Using archival footage dating back to Ai's adventures in the New York art world in his 20s, Klayman traces his evolution as a creator and as an activist. full review

Though he has paid the price, Ai is a pathfinder in this new phenomenon in tactical insurrection. Never Sorry is a new-style profile in 21st-century courage. full review

Ai admits that he's become "a brand for liberal thinking and individualism," though that's nothing to be ashamed of -- at this point, his Warholian talent for self-promotion may be the only thing keeping him alive. full review

The story is enthralling, but it's not over, and there's no telling where it's going. Which makes what we see on screen all the more involving. full review

One of the most engagingly powerful movies of the year almost completely on the strength of Ai's rumpled charisma and the confusion it creates in the bureaucratic mindset of the Chinese Communist Party. full review

As this sometimes haphazard documentary shows, Ai won't stop talking. Or blogging. Or tweeting. full review

A useful primer, though it also focuses a bit more on the activism than on the art. full review

He may still seem enigmatic, but we don't need to know his deepest thoughts. The intensity of his daily life and the persecution he continues to face is more than enough to understand who he is and what he is enduring. full review

Klayman had full access to Ai, 55, following him around for two years. The sweetest footage involves Ai and his mother. full review

Ai Weiwei is a crucial figure of East-West cultural communication and contemporary history, whose middle finger extended at the centers of power stands for a rising tide of global discontent. full review

The fluidity and convenience of digital moviemaking tools explain some of its freshness, as does Ms. Klayman's history as a budding documentarian. full review

The film's greatest distinction is its intimacy. full review

One can't help wishing the subject would make his own, more complex cinematic self-portrait. But for now, Klayman has provided a valuable introduction to a man everyone should know. full review

Ai Weiwei: Never Sorry accomplishes what the best works of this sort do: Take a great, compelling, widely known story and make it deeper, fuller and better. full review

Ai Weiwei: Never Sorry is a portrait of a brave (or simply stubborn) eccentric in action. full review
