The NC is still a guilty pleasure for me, but I'm not hitting F5 waiting for his next review. I think people like the NC and the Nerd are at their best when they are not in angry mode and giving their honest, thoughtful reflections. The anger can be funny, but it needs to be used more sparingly as an addition to the review and part of the humor as opposed to the main theme. Sort of like a spice. A little bit can add a pleasant flavor to the mix but too much is overpowering and it becomes a substitute for substance. What is lost on people is that it is not the rage itself that is humorous. What makes humor funny is when people can relate to the frustration on a empathetic level. Making angry noises is not funny, neither is throwing in random cusswords and crude analogies.
Comedy is an art not a science, you can dissect the fundamentals and elements of what worked for other people, but if you can't make that special, empathetic connection to your viewers your work means very little. Everyone has their own unique style and when you are not true to yourself people will take notice.
