A lot of CG work goes into a single episode of Gotham. The show has become more sci-fi as its went along too. Especially in Season 2.

I was exaggerating a bit, but the point is that virtual buildings and skylines are, by definition, mostly static. They require very little in the way of actual animation, and are thus far easier to pull off on a broadcast TV budget than it is to make superpowers or alien creatures look believable.
