this not an easy picture . it require patience and commitment . it a poetic movie about the urban heaven . about real people . about love and about madness . reygadas be truly an author . he turn a conventional history in to a great ride through emotion and feeling and in to the overwhelming city of mexico . either you love it or hate it and no one come out of the theater without a comment or a reaction . the movie have the power to move you in a positive or in a negative way . and i guess that something to be thankful about . mexican film and in recent year and be mostly easy go urban comedy . this totally different . a prove that we can make different story that reflect the sometimes surreal life of our country . this be one of them . with no professional actor and the movie feel honest and . the cast it in a very natural level . the sex scene be not as important a they seem . sex be finally a part o who we be and and we be use to see great body make love on the screen . it not easy to see real people do it and because we may see ourselves in them . and when someone throw your reality at your face and you can hate it . but batalla en el cielo do that and even more represent take that reality to another lever and turn it in to poetry . and that it just fantastic .
