If the director was trying to make the viewer uncomfortable, confused and depressed then he accomplished that much.The movie was basically about a broken woman and a troubled,obviously hurting young man who she decided to take in to her home.The events that took place during the film were slow,awkward and strange to say the least but not in an enjoyable way.The movie went absolutely no where and even tho the acting was very good it couldn't make up for everything else it was lacking.

Why would a new mother abandon her child and husband? It's an intriguing question, usually surrounded with heavy social stigma, since any mother denying her maternal instincts is either downright abject or at the least a bad excuse for a person, or so society swiftly judges. Nevertheless, it happens and it begs an answer. Those looking for one will not find it in Mammal. In fact, though at first thought the movie seems to revolve around a mother who accepts a second chance for motherhood, that may be too much of a generalization. But some sort of connection, both emotional and physical, between two vastly different but equally lost souls, is certainly in order in this narrative.Margaret abandoned her family soon after her son was born, and she now has been out of their lives for 18 years. When news about her son's disappearance reaches her, not much sorrow is demonstrated. Nevertheless, around the same time, she accepts a wild kid from the street, roughly the same age as her own child, to live with her. The big question obviously being why. A simple act of generosity? Or perhaps another shot at maternity, after foregoing that responsibility all those years ago? For a while, the latter option seems to be the case, but when things get overly physical between her and the boy, Joe, that theory doesn't hold up any more. If motherhood is indeed Margaret's objective, she has some odd notions of the concept at least.Unfortunately, Mammal - the title suggests a nurturing nature to their relationship based on maternal instincts, though there's also an undeniable social aspect to it as well, so one can look at it from both angles - is short on motivations. It's not Daly's intention to spoon feed us all the answers, which is fine, but there's simply too few of those concerning the various characters' actions to go around. Things happen as they do, while particular reasons are entirely up to the viewer to come up with. It makes Mammal a rather hollow film. Thankfully, there's strong performances throughout, which do make us care enough to stick with the protagonists rather than lose all interest entirely. We hardly get to know these people to the extent that we should for Mammal to deliver the gripping drama it feels like it wants to, but as fellow mammals we sympathize enough to feel some emotional connection to stick with them for a good hour and a half.
