One could argue that “Supergirl” was set up for failure given the way the character was introduced into the DC Universe in Gunn’s “Superman”: drunkenly stumbling into the Fortress of Solitude looking for her dog Krypto in a blink-and-you’ll-miss-it cameo.

I actually thought this scene was really funny and was looking forward to her movie; I thought it could be a comedy, like maybe she goes on a super-bender and hijinks ensue. Then the trailer dropped and it kind of seemed like it explained the whole movie, or enough that I could fill in the blanks without actually seeing it, and it looked like yet another standard superhero movie. It’s also the second movie in a row where Krypto gets in trouble, and I cannot stress enough how much I do not want to see a movie where the dog is in mortal peril.
