I don't think this one was meant to be nearly as funny. It focused much more on the "improve the writing of the plot and characters" aspect of this Abridged Series than on the humor.I don't know, I've got mixed feelings about this episode. It felt a lot more ham fisted than most of the other episodes and I didn't find it as funny as the others.
I don't know why that is, I'll probably have to think on it longer.
