Beginning with the firstIron Manto this year’sCaptain America: Civil War, the Marvel Cinematic Universe is one of the most lucrative movie franchises of all time. But why can’t the average moviegoer remember a single melody from any of their soundtracks?

The themes that do succeed in this regard, however, are often buried under other sound effects, like Cap’s theme inCaptain America: The Winter Soldierdrowned out by the museum’s voiceover.

Maybe something likeSpider-Man: Homecoming, which claims to give offJohn Hughesvibes, could be the exact kind of musical injection this franchise needs.
