See, Zack Snyder? It's not so hard. I wouldn't worry about yours if I'd seen something like this already. I admit I could do without Supes stealing one of Will Smith's one-liners, but John Noble's a great Brainiac, and Matt Bomer was an early contender for Bryan Singer's Superman Lives back when he was a total unknown, so it's cool that he gets a do-over.
It also reminds me that Kandor was the original city Under the Dome.
