In There Will Be Blood, Paul Thomas Anderson got earth’s most intense actor into the role of a megalomaniac and essentially just let the camera watch Daniel Day Lewis volcano all over everything. Here he does the same with another great slow-burner, Phillip Seymour Hoffman, though the results here are even more diffuse in terms of plotting. Joaquin Phoenix plays the Master’s acolyte and foil, and does terrific but often overcooked work; you get the sense that Hoffman is not the only three-named intensity-monger that Phoenix is bending over backwards to impress. It’s an engaging movie to look at, but as with There Will Be Blood, I wind up feeling there’s a certain emptiness to the endeavor. So many of the scenes feel like exercises in a Strasberg seminar; there’s a great deal of emoting, but not a lot of emotion. Part of the trouble is that the movie is so fearful of being about anything specific that it winds up not being about anything in particular. The wish to belong, the lure of alcohol, rationalism vs spirituality, male friendship, PTSD, American vacuity . . . they’re all toyed with as themes, but Anderson puts down no significant bets on any of them. So you’ll remember people laughing, crying, shouting, fighting, and kissing, but not why.
