Grim, terse and jumpy, '71 effectively evokes the chaos of early-1970s Belfast. A little too effectively, perhaps, since some sequences are as bewildering as the four-way civil war the movie re-creates. American viewers may wish the film came with both subtitles and a study guide.
'71 can be recommended, though, to viewers who don't mind a little bewilderment in the cause of an authentically visceral experience. After all, Northern Ireland residents who lived through The Troubles were probably also confused much of the time.
