Hmmm... I don't know if it's so much overlooking that's required, but something more than a cursory glance. You can make a case for "see, White girl with good positive powers, Black guy with dark scary powers" or even "Why the Black guy gotta wear black? Is this 1990s Power Rangers?"
BUT I think if we actually see what their powers are, and the core conceit of their abilities, that the show seems to be well focused on: that they need each other, it's really hard to make a case for "obvious racism" when the White person needs the Black person and the Black person is much MUCH more powerful than the White one. Also... interracial couple counts for *something* especially in the absence of any actual aggression.
Plus... if we actually explore how Cloak operates in society as someone who people feel is dark, scary and powerful, then we're actually exploring racism instead of just being racist. That's actually a lot cooler than giving him a power that has nothing to do with how he's perceived in society. There's a reason these characters have endured and other actually obviously racist characters have fizzled out.
