The word "epic" is used far too frequently in my estimation. Even I am inclined to overusing it. But the tale Robbie Morrison tells here is epic in both definitions of the word. It is a tale that proves both epic in scope and it is an epic in form.
Alas, the artwork by Dave Taylor isn't quite as good. Taylor presents some amazing images - such as the reveal of Clara/Kali - but most of the issue's artwork is mediocre, at best. It's not enough to detract from Morrison's story but many of the proportions are odd and Taylor's pencils get sloppy past the middle distance.
