Comedy is so subjective. You could be in a room with 400 people laughing at a joke and you could just not think it's funny. You're just sitting there like 'Am I in the twilight zone? Why is everyone laughing?' It's such a personal thing. People have such a personal visceral response to comedy.
During the 80s and 90s we all became consumed with ourselves. In the 21st century we've come back to simpler times. People are struggling economically and this has forced them to scale back the material aspects of their lives and realise the beauty of finding the simple joy in being with the people we love.
