Positive Points

Milly Alcock clearly threw herself into this role, and it shows. This version of Supergirl has a real unplanned confidence and shows an amazing level of toughness that is unlike any other version from the DC Universe. At the same time, the visual effects can go from being breathtakingly real to simply being amazing — thus allowing you to feel part of huge yet completely authentic alien environments. It will also have heavy and explosive action sequences like you'd expect from the latest Hollywood film. Krypto is an absolute delight every time he shows up, and the soundtrack has a personality of its own. You can also tell James Gunn was genuinely trying to carve out a separate identity for Kara rather than just making her Superman's cousin — her backstory is darker, more wounded, and that's an interesting creative swing.

Negative Points

The story is where the film quietly lets you down. At its core, it's about rescuing a dog and getting revenge on a villain who, frankly, never feels threatening or interesting enough to justify the journey. Krem is just... there. No real menace, no memorable moments, nothing that makes you lean forward in your seat. And because the plot is so thin, there's barely any room for the characters around Alcock to breathe — most of them come and go without leaving much of an impression.

The disappointment of the clear emotional basis is apparent. There was obviously going to be a significant relationship based on Kara's past, but because of the overwhelming use of CGI, there's a pacing issue with the film that takes away from the separation of the action scenes and the softer emotional moments. You see a glimpse of something with a deep meaning only to have it quickly go away as we are thrust into the next action sequence.

Overall: Supergirl is a movie that has more visual appeal than substance. Alcock deserves a better script; the premise needs a more interesting antagonist; the audience deserves to have a story that sticks with them long after the movie is over. Although it's not a terrible time at the movies, it will probably only be enjoyable when you see it and you will have trouble remembering it within a week of viewing.
