It's not a "chuckle at the Father Ted style wry Irish humour" comedy. It's a bleak "The moments of gallows humour serve to briefly, and artificially, raise your sensibility from total despair, only to allow it to be smashed down again, much in the way that a bare knuckle boxer might pick his downed opponent up by the hair, so that he can smash his skull back down into the canvas once again" kind of humour. If that sounds like it will cheer up your friend, then good luck.
