. . . and it not really even about lucia . lucia y el sexo be actually about lorenzo and lucia novelist boyfriend and and the consequence of a sexual encounter he have in the past which have lead to a catastrophic event in his life . it a languid and tempestuous poem of a movie and tell in a non linear way by the extremely ambitious julio medem . a a novelist myself and i deeply relate to lorenzo blurring of reality and imagination . your character must be real to you in order for them to live and breathe on the page and and so much of your own life go into the character that the line of course do blur . and then there the subconscious and which can not differentiate between fantasy and reality . medem understand all this very well and and his depiction of it be remarkable . the title and i believe and refers to lorenzo past ( the sex and what happen a a result of it ) and and his present ( lucia ) . paz vega and tristan ulloa be stun a the two lead vega with her fierce intelligence and ulloa with his tormented vulnerability . i would have give this film a 10 if it hadn not be for the fact that the most pivotal scene be shoot in an incredibly vague manner and which leave me confuse a to what have actually happen until much later in the movie and but it be a brilliant and heartfelt experience nonetheless .
