Other reviewers have gone into great detail of the plot and there is no need for me to duplicate information. Daniel Day Lewis is an actor who chooses his parts with great care and, if the media is to be trusted, prepares for his parts with meticulous and detailed care. The issues of the IRA and Northern Ireland are complex, deeply rooted in both cultures and very difficult for an outsider to judge.
It is very difficult to empathise with people who use terror and indiscriminate bombings to make political points but this film makes a good attempt. It is difficult to fault any of the performances and it will certainly provide food for thought.
