Metacritic reviews

This terrific and sublime experience, and strikingly original film, is mandatory watching for the adventurous viewer.

Off-beat and punk-spirited.

Helmer Lenny Abrahamson (“Garage,” “Adam & Paul”) puts the pic’s eccentricity to good use, luring in skeptics with jokey surrealism and delivering them to a profoundly moving place.

For a film that champions talent that takes risks, Frank can sometimes feel a little too conventional. The real Sidebottom's wayward genius would be a hard fit for any story arc, but Frank does a good job of dipping into surrealism and pop in equal measure.

Dreams of rock stardom become a warped reality in this barking-mad but affecting comedy about the side-effects of being a non-conformist genius.

Though more in love with its silliness than the insights buried inside them, Frank works to amusingly irreverent effect when combining the two.

The film boldly raises the unanswerable question of whether it's better for an artist to safely isolate his work or tweak it a bit so as to share it with the world.

If you'll pardon the cleverness, Frank takes time to wrap your own cranium around, faults and all, and that's a wonderful thing.

With Frank, Abrahamson cultivates a mystical hour of prog-based shenanigans before he - and his film - begin to lose their collective heads in a muddled final third.

The mash-up of elements combine with a singularly unpleasant roster of characters to create a work of genuinely off-putting quirkiness.
