I suggest dropping the *isn't* and describing what it is. With the *isn't,* a reader will have to infer the opposite of the adjective you use. I propose

**multifaceted**

> having many facets (see FACET sense 1) or aspects  
> *a multifaceted approach to health care* [m-w][1]

> **facet**  1: any of the definable aspects that make up a subject (as of contemplation) or an object (as of consideration)  
>*Each facet of the problem requires careful attention*. [m-w][2]
