I think it is the opposite actually. They only appear complex at first glance. There is nothing all that complicated about the theory or the graphical illustrations if one takes them a step at a time. Like anything else it then becomes easier with practice and thought. The diagrams might look overwhelming and busy at first, but that's because they illustrate an end to end system, and it doesn't take long to get comfortable with them. Haist's diagrams are nice and clean, but they are pure H&D, meaning things like flare are not considered. Haist says this himself. They make sense if you have a good understanding of tone reproduction theory, but for the "average person" they don't show much about tone reproduction.
