The subject matter is fairly universal - the frustration of your beloved not loving you back in the way you want, and the existential loneliness it triggers. Most people would choose to drink, seek casual sex etc... Our director is an artist, and chooses to make a film.
There's definitely interesting bits beyond the titillating set up that involves real sex and sexual tension. All these different people come in, and as the project progresses, we see how different expectations, subtle manipulations, desires and different levels of hypocrisy clashe and dissipate. There's no surprise. We all see what we want to see, and at the end of it is miscommunication and broken connection - existential loneliness, in one word.
Many (including director's mother) seem to find it uncomfortable to see the director dares to turn this process into a work, but I think it's rather common for a young artist to display so much self-consciousness and ambition -the belief he could turn his life into an art-. My criticism lies in that he remains unclear what he wants and where he goes with this project. The only thing clear is his longing and obsession for his lover in Mexico City. When he is so preoccupied with him, it's no surprise that he fails to connect to any of the participants, to the project itself and ultimately to himself.
I hope Isidor reaches certain clarity with more experience, age and deeper contemplation. Then 'Acts of Love' would be viewed as a little remnant of his process, a brain storm of his art and life.
