Director Paul McGuigan’s best film to date is still the English gangster film Gangster No. 1 from 2000. However, the major problem with Gangster No. 1 is the same problem that plagues McGuigan’s latest effort Lucky Number Slevin. Both films suffer from a very weak final third act but while Gangster No. 1 was salvageable, the direction that Lucky Number Slevin takes completely ruins what initially promises to be a good film.
