In a word...

Rating: 9/10 (28 October 2010)

Excellent.
The way Bale portrays Patrick Bateman both engages the character with the audience and keeps us guessing his true nature. The constant changes in personality given a further presence of darkness and intrigue, which is only heightened by the ending. The artistic feel of the film, which I feel if symbolised straight after Bateman kills someone then is seen drawing the details of their death as an infant gave greater depth to both him as a character and the story, and made it all that much more complex.
However, there are some minor details which personally, took away from the realness the movie delivered. Such as Bateman standing on the stairway, simply watching his victim run away then just 'dropping' the chainsaw which, lucking for him, hit her. Also, the confrontation with the police where a single bullet blew up and destroyed two cars was both over the top and unnecessary.
