Eileen Jones (hilariously) does not like There Will Be Blood:
To rub in this sentimental view of the rich and powerful as spiritually barren—cigars, mansions, private bowling alleys, and yet they cannot love!—Plainview has to acquire and reject some family members. He gets hold of an adopted son, H.W. (Dillon Freasier). At first he does seem to love the kid with an almost creepy fervor. There’s this scene where they’re both on the floor after the boy is deafened by an explosion, and Plainview is sort of pawing and mauling the kid’s head while the kid goes "Mrrrraaawww!!” I’m not quite sure what that was, other than the only preparation the audience is going to get for Plainview baying "Draaaaiiiiinnnnagggge!!" later in the film. Incoherent yelling’s a sort of motif in this movie.
Jones has great fun quoting critics on the movie's greatness: Roger Ebert calls it a "force beyond categories." Where one might differ with her is whether all the weirdness in the film is a bug or feature--evidently she wants her rapacious capitalists and religious zealots played more sensibly.
