A musing on loneliness, depression, and the end of a friendship, writer/director Martin McDonagh's The Banshees of Inisherin offers stand-out performances from both Colin Farrell, as the dull but otherwise likable enough Pádraic, and Brendan Gleeson as his longtime friend Colm, who announces one day he wants nothing further to do with his best friend and will perform physical harm to himself should Pádraic refuse to leave him alone.
The film never reveals the catalyst for Colm's decision to distance himself from his friend and work in peace on his music nor offers an ending to the tumultuous situation the two become locked into, instead offering a front seat at the escalation as Pádraic's inability to accept the situation, and Colm's bizarre threats and actions as a brutal response leading to an apparently unresolvable stalemate as the credits roll.
