i don't know, i didn't see much freshness from the superman returns-man of steel-BvS installments. and a common complaint for superman i've heard is that he's kind of boring because of the all encompassing nature of his powers paired with the overall pureness of character. perfection is boring. his flaws always seem contrived and superficial.
marvel characters are usually variations on funny jerks with a heart of gold, brilliant and cocky and witty but suffer from the flaw of hubris. tony stark, peter quill, dr. strange and to an extent ant-man are all basically the same dude personality wise, but it works because that's a really good character to build a film around. captain america is the closest comp to superman character wise, and he's still kind of limited on powers scale and i'd argue he works best as a foil to the other dudes.
