May as well reuse that stuff I suppose. It's just that I don't think I've seen a show do that in a while. Does The Flash do it with the running shots?
Maybe some of the overhead shots of lightning racing along the streets. And I'm sure they reuse some digital models and animations. The shot of the CGI Flash dangling in King Shark's grip reminded me of the shot of the CGI flash dangling in Grodd's grip.
