"Monogamy" gets off to a fine start with its natural performances. It also provides some incisive commentary on all the nonsense and stress that go along with getting married. And then after an improbable plot point, it just runs out of ideas and steam.(Even before this, any scene involving Theo's friends was sucking the oxygen out of the room.) After a while, I was so desperate for any sign of life that I would have happily accepted any cliche you could think of, but no luck there, either. In the end, the movie gets the tone of sexual frustration right while at the same time making the audience extremely frustrated.
The film, although quite slow moving, is shot very well and it moves along at it's own speed quite nicely. Messina and Jones give good performances, and do what they can with a script which could've used a lot of work. The film's themes strike close to home with anyone who is about to get married and is unsure of the decision. The fear of the commitment and the temptations of voyeurism take a huge toll on Messina's character, and his daily life of putting up with the corny married couples while taking photos couldn't help the matter much. The film was a little bland, and although I did enjoy it, I felt like it was a few scenes were a bit unnecessary, and I felt myself losing interest in the story and the characters three quarters of the way through. Overall, I give Monogamy a 6.5/10, noting that with the budget they probably had to work with, it was a good effort, although it could've been made more interesting through the cinematography and mise en scene, in particular with some of the colors used and the lack of symbolism throughout.
