Here are some reviews for a movie: 1. It's a quasi-religious fable about a man haunted by the past and facing a profound moral and existential crisis in the present, and it's a dazzling display of virtuoso cinematic technique and showboat performances.
2. Lubezki's cinematography, paired with Antonio Sanchez's jazzy, percussion-heavy score, creates an atmosphere of explosive tension that lingers strongly, even throughout Birdman's more satirical and fantastical beats.
3. Birdman, more than most, seems a film that deserves a second viewing, not only to admire the work of Keaton and his co-stars, but to delve into its many layers.
4. Birdman is a tour de force, a heady mix of dark comedy and psychic meltdown with energy vibrating from every frame.
5. Iырrritu serves up a truly fanciful production that is long on characterization but woefully short in the realities of the theatre.
6. Birdman has wings, for certain, even if you find the feathers sticking in your throat now and then.
7. Michael Keaton's performance as ex-leading man Riggan Thomson sees this former star reborn.
8. It's a film no one expected but one for which we're utterly grateful.
9. While Keaton is a tour-de-force, Fight Club star Ed Norton is similarly rejuvenated as co-star Mike.
10. Even if you don't like Birdman, you will be unable to forget its unique ability to disguise meticulous, well-rehearsed craftsmanship as irresistible improvisation.

What was the overall consensus about the movie?
A thrilling leap forward for director Alejandro Gonzрlez Iырrritu, Birdman is an ambitious technical showcase powered by a layered story and outstanding performances from Michael Keaton and Edward Norton.
