Sexual frustration. Second thoughts about going through with an impending marriage. The maturity of realizing that infatuation wears off, and that real commitment means remaining with someone even when life becomes difficult, or merely mundane.

These are the issues that "Monogamy" (2010, directed by Dana Adam Shapiro) deals with. The male lead, a photographer named Theo (played by Chris Messina) struggles with all of this, and, ultimately, lacks the maturity to follow through, unable even to provide the vital support of attending an open-mike night audition for his aspiring musician fiancee Nat (played by the stunning Rashida Jones), or to regularly visit her even after she is hospitalized.

This film has been criticized as being overly slow with a not particularly well-developed script, but these criticisms are unfair. The film deals with uncomfortable issues and the story takes the time it needs to, while respecting the viewer's ability to deconstruct the Theo-Nat relationship for himself/herself.

6 out of 10.

As a side-note, in my opinion, this is Rashida Jones' sexiest film.
