The Clown Prince of Crime
Super Freak
More 'realistic' though? Superman, Green Lantern, Aquaman, Shazam? Errrr.
I think a film can have a sense of realism even if the characters aren't realistic. Look at the Nolan Batman film, it's fantasy and silly...but there's still a sense of realism to the world, the acting, and the technology in which all the silliness takes place.
Maybe in the case of BvS, part of the realism comes from how society, the governments, religious people, and other countries view these powerful beings. There's already a glimpse of that in the BvS trailer. That's something the old Christopher Reeve films ignored. The MCU has also explore that aspect, but maybe not to its full potential. Realistically speaking, if Superman was real...the world would change.
