good actor . great story ( ian mcewan be a legend . ) definitely read the novel of the same title before see the film . this film be fantastic . i finish read the novel two day before see the movie and and although it have it differences to the novel and i be grip . the screenplay make necessary change to the story plot . for example joe rise be a scientist turn journalist in the book and this would not have be very effective on screen and and so they make him a lecturer . spoiler below the end scene be absolutely fantastic and i be expect the novel end with the gun to be use and but the knifing be extremely shocking and poignant . similarly and the small clip a the credit run and of jed in an institution match well with the 2nd appendix of the novel . eerily emotive . represent represent the film maker do a great job of turn the book into a film and and i recommend this movie .
