Not recommended. It's worth noting that there’s no Inisherin. The name was invented by Martin McDonagh (Three Billboards Outside Ebbing, Missouri) for his eponymous new movie, filmed on spectacular Achill Island. And following that fanciful theme, the characters that populate his Irish village seem the unpleasant variety of Celts - - stubborn, brutish, and stupid - - stereotyped in numerous other films. The point of it hinges on two former friends, Pádraic (Colin Ferrill, In Bruges) and Colm (Brendan Gleeson, In Bruges) who have fallen out because one thinks the other too boring to endure. The spat escalates to the point of gross, and possibly allegorical, self-mayhem . . . off camera, the 1923 Irish Civil War rages; however, the characters are so under-written that the motivation is unclear and the story, uninteresting. The only sane person on the island is Pádraic’s sister (Kerry Condon, Three Billboards Outside Ebbing, Missouri), but she, inexplicably, departs. Nice landscapes, though.
