Anyone who has an issue with the NK scene is wrong, that is questioning if it is within the scope of his powers. Now everything else about the scene and how it ended up there, sure, that was all pretty stupid. But a guy who can move planets at will at normal strength should be able to move a continent when greatly weakened. The other issue with the continent holding together, etc, is a different matter altogether as comic book physics and real life physics are not one and the same. As long as it isn't Hercules towing Manhattan, you just gotta suspend your disbelief.
Although I don't like how low-powered Supes was in the Timmverse, I do love the fights from the JL/JLU series, the Darkseid battle and the Captain Marvel battles especially. Fun to see Supes using the 'ol double-axe handle on Darkesid-that was one of his signature moves in Swan's comics. That and he loved grabbing people by the leg and chucking them into the sky (people who could take it, obviously).
