I watch movies more with emotions than analysis. Oftentimes I judge by whether the story or the characters touch me.
In the case of Hoy y mañana, I don't feel for the protagonist at all. She wondered aimlessly and lived by instinct. She had a lot of people caring for her, her uncle, her well-to-do pregnant friend, her boyfriend, and her dad, who seemed to have been trying to instill some sense into her forever. Even her prostitute friend was generous and helpful. She used all this kindness surrounding her, and then carelessly tossed them aside, like used tissues. Her aspiration, the theater work, which is supposed to be her identity, seemed shaky, without a promise to be in production, and ran by a slime.
The production quality of the movie is plain vanilla. The story line is just a digital camera following the protagonist around the streets over night. The clients she encountered seemed unconvincing. The hand-held camera work, Blairwitch Project style, went overboard. I had to turn away from the screen a few times. There's really no point in creating a style just for the sake of being different.
There are so many good movies out there, even if you are into indies and foreign films. Don't waste your time on this one.
