I found the the film to be pretty trite and one-note. I can identify a few fundamental flaws why I felt this way.
The first is the impenetrable character. In
There Will Be Blood, the impenetrable protagonist was the enigma. We watched this character to learn more about him and his actions and motives. It's important that the main character was the real question of that film.
In
The Master, the structure of the film is that of the outsider coming into a brave new world. Joaquin Phoenix plays an impenetrable protagonist, but Phoenix isn't the enigma, The Master is. So we're less interested in the dumb, drunk sailor caricature that heads the film. Further, Phoenix's performance adds nothing of depth to the one-note stereotype nor does Anderson's attempt to add a single humanizing memory of a girl.
We want to try to get inside the Master's world and his motives for starting this group or even helping Phoenix's character. Instead, we're burdened with Phoenix flailing around with a one-note character. And the Master's character is no different. Nor is Amy Adams' character. With the exception of sudden outbursts, Hoffman plays the Master as one would expect. Charismatic at dinner parties, controlling, yada yada yada. It's all very... expected. There is no spontaneity, and, thus, there is no life.
Advancing the feeling of being one-note is that nobody changes or evolves their positions. It makes me feel as if this could've been a nice 20 minute film, but at 2 hours, it more than makes its point, over and over and over. Perhaps if Phoenix's character ever changed, then we could see variances in the Master or the religious group.
Typically, with the "outsider going into a new world" structure, we would see reflections of the world on the main character (see
Last King of Scotland for a very classical example). But there is nothing to Phoenix's character that we don't learn in the first two minutes, and as a result we learn nothing about anyone else from his reflection.
The different entities could play off each other. But they don't. Drama is conflict, and there is very little here. So while Anderson's penchant for over-scoring is in full effect, there are few emotions and fewer ideas. Even the bond between the Phoenix and Hoffman seems like a misguided attempt for Anderson to graft on a father/son relationship, that falls completely flat in an ending that
basically just mirrors There Will Be Blood. The "son" returns to the "father." The father is now in an opulent throne room, mildly more successful. And then the father casts away the son.
Overall, it's a good-looking, but very hollow misfire.
