It was average, in my opinion, nowhere near as good as "Gone Maggie Gone". The first act was too long, so the main plot (although not really rushed) was over too quickly. Some good Grampa/Homer relationship stuff and a few good lines and visual gags (Colin Farrell is out of prison gag and "Ah, my son's first stroke"). As expected, a fair amount of Irish stereotyping (leprechauns, yuprechauns and more leprechauns) and obvious humour, but it wasn't that bad. Meaney wasn't bad. The Once reference was funny. Animation was brilliant once again. 2.5 or 3/5.
