Kung Fu forms are not that complicated once you put the time and effort to understand what’s behind it all.
A teacher told me that about Quantum Physics.
Well, if you convince yourself it’s too complicated than it probably is 
I think some traditional systems have made themselves to complex though. Even different branches of the same system… I might see one branch with 5 forms and then another with 100+. Quite a few traditional systems seem to have more of a performance element to them than they care to admit either (probably due to communist involvement in performance oriented wushu). It’s always amusing to hear some groups bad mouth modern wushu when some of the forms they do in public and competitions are about half as martial in content and organization than the old compulsory form
