I admittedly liked Hancock as a Superman clone. Far more than I like Blue Marvel, Sunshine Superman, Icon, etc., if we're talking purely about characterization and backstory. Wish Marvel owned the rights. That's not to say that Hancock wasn't problematic, including the fact that his natural mate -- in the form of a White woman no less -- was his Kryptonite. (But it's the gorgeous Charlize Theron and, really, what cisgender heterosexual male wouldn't happily be weak to her element, if the Fates deemed him so lucky???)
Blue Marvel's problem is that no one will ever be curious or nostalgic about his beginnings the way that people are curious and nostalgic about Kal-El's origins. Fewer still will see the tragedy in it, even though in the real world we're still faced with overcoming those same challenges.
