Summarize the following movie reviews:

1. El diseńador Tom Ford debuta como director de cine con el retrato íntimo e introspectivo de un personaje en crisis existencial. Una película sensible y madura, si bien peca de cierto exceso de esteticismo.
2. Director Tom Ford intends this film to be a celebration of life, but it misses the mark. The balance of this sorrow-laden film is too heavily weighted towards the depression side of the scales for that. Great performance by Firth, though.
3. ...offers a raw view of the gay experience that has nothing to do with sex.
4. Tom Ford's directorial debut A Single Man is unspeakably gorgeous to behold. From the glorious cinematography to the impossibly beautiful actors and actresses; no frame is wasted on anything even close to ugliness.
5. Ford's film is an addict for prettiness and in the process resembles an excessively over-designed photo shoot rather than a film.
6. What keeps the film anchored is the growing unease that Firth exudes in quiet, crushing waves. He's always at his best, single-handed.
7. What the film does fumble is the relationship between George and a student (Nicholas Hoult) whose gaydar he must have set off.
8. A rare thing-a mainstream, melancholy love story, haunted by the past.
9. As Ford's first film, this story, based on a novel by Christopher Isherwood, must have had special meaning.
10. What's remarkable is how Firth, with the smallest of gesture or nuance, lets us see this man's heartbreak without ever letting it burst through his carefully controlled surface.

Summary:
Though the costumes are beautiful and the art direction impeccable, what stands out most from this debut by fashion designer Tom Ford is the leading performance by Colin Firth.
