What is the word I'm looking for?

I'm looking for a word that's means something along the lines of "including many different factors that are all interwoven and inseparable". Kind of similar to the definition of the word "holistic", but there is a different word I'm looking for. I'm using it in the context of social issues and how people tend to oversimplify the solution to very complex problems. For some reason I wanted to use the word "dynamic" but I don't think that is the right word. Please help my fill in the blank!!

"I think the solution is much more _______ than you are making it out to be"
