I think it was unfair. For all we know, Mr. Caldecott may have a priest visiting him daily. Maybe his family say the rosary by his bedside every night and the Angelus every day at noon. Maybe he's had Last Rites and has reached the final stage of dying where life has gotten very, very basic: morphine, ice chips, a few words, sleep. Attacking a dying man and his grieving family just comes across as so loathsomely small and mean and I don't see Catholic virtue in it at all.
When my paternal grandmother was dying her sons all would've watched soap operas and feigned enthusiasm if it would have made her smile one more time. Whether Mr. Caldecott's favorite movies are to my taste or not, I understand what Mr. Caldecott's daughter is trying to do. God bless her and him.
