Definitely the best movie I've seen in a while. Children of Men is Cuaron's masterpiece (the guy who directed Y Tu Mama Tambien). The linear storytelling is refreshing and engaging, and this film features some cinematography (specifically several long take tracking hand held sequences) that I am still trying to figure out how it was accomplished. The final act is a marvel of technical filmmaking ability that is not oversaturated with CGI.
Owen's best work yet, with great supporting performances
