The notion of reimagining established characters and altering their circumstances holds considerable appeal, even if it's not entirely novel given the prevalence of multiverse concepts in both Marvel and DC comics—and subsequently, films—which have been used to reconcile inconsistencies in timelines and events. The show’s execution relies on a combination of computer-generated animation intended to evoke the feel of comic books, occasionally achieving noteworthy effects. However, the quality is tied directly to the narrative being presented; some episodes lean toward campiness while others demonstrate considerable promise and even introduce characters previously unseen in Marvel's other media. *What If...?* builds on a strong foundation that hinges on its storytelling approach. Overall, the series merits an 8.0 out of 10.0 / B grade for its faithfulness to the original concept and its courage in adapting it into an animated format.
