Well I think a lot of things are more HIT/MISS these days. Maybe people's tastes have gotten more diverse with all the possible channels/avenues of entertainment in comparison to the past.
...Mrs Brown's Boys is something I feel a great deal of Shame and Second-Hand Embarrassment from. It's prolly the most unfunny excuse for a comedy on our screens over here. :( There was a film. It was popular. :( my faith in everything was damaged.
