In this article, I argue, adverting to critical practices, that film adaptations are comparable with the comics that serve as their sources. The possibility of comparison presumes the existence of covering values according to which these comparisons are made. I raise four groupings of covering values for comics—narrative, pictorial, historical, and referential—and show how they apply to film adaptations as well, and argue that a fifth kind of value, fidelity, is relevant to comparisons of source comics to film adaptations. I close with a discussion of different types of fidelity that might be brought to bear in evaluation.
