Krypto is one of those things that keeps Superman from being anything but a joke, and this scene alone shows why. Even with a ridiculous budget, it looks ridiculous and undermines whoever is on the receiving end of him (because we know the precious doggo won't get seriously violently hurt in any fight).

He is a fine character in a comedic work or spinoff version, DC is riddled with those and they have their place. But the fact that Gunn chose to use him from the very first trailer tells me how little I'd care about this movie.
