So many haters out there who didn't get this movie at all. It's not meant to be taken seriously at all, it is written to be enjoyed and laughed at and is perfectly British in every way.
Yes, some of the jokes were more childish than others but what the hell, just go with it and laugh at the silly little innuendos and potty humor. Life is way to hard these days and we all need a break from it and this movie is certainly that. There are so many different forms of comedy, and yes this one did take the low road often, but if you just allow yourself to turn off and have fun it's great.
The people saying that the experts were just being insulted and had their time wasted need to stop and think about the fact that this is not the first tike that Philomena has done a show. They must have seen the other shows, or at least read and heard about them first. They knew what they were getting into, they chose to go on the show and they were not ridiculed. Everyone was in on the joke, its not a mean show that leads them on thinking it's real and tricks them into looking stupid.
Get off your high horse, not everything needs to be highbrow and we all need a break from life these days and Cunk on Life gets you our of life for a bit.
