Legion of Super-Heroes (2023)
As Krypton explodes, the teenage Kara is launched into space, arriving on Earth years later. Now she's been here for two months, and she's already in action as Supergirl. Unfortunately, she tends to cause a lot of 'collateral damage'. After needing to be rescued from Solomon Grundy by Superman and Batman, Superman takes her to the 31st century and suggests she train at the Legion Academy to get a handle on her powers. At the same time, back in the 21st century Batman deals with a break-in at STAR Labs. It soon becomes apparent that present and future are dangerously linked.
This is part-humorous 'coming-of-age' story/part-action, and it's carried by Supergirl (Batman and Superman only appear near the beginning and the end, Flash appears near the beginning). We get featured appearances by Mon-El, Brainiac 5, Timber Wolf, Shadow Lass, Triplicate Girl, Dawnstar, and others. Artwork/animation is on a par with other Tomorrowverse movies. Supergirl has a cute character design, and is engagingly acted by Meg Donnelly (who I could absolutely see as a live-action Kara). Jensen Ackles, Darren Criss, and Matt Bomer return as Batman, Superman, and Flash (btw, this movie contains this continuity's first onscreen pairing of Batman and Superman, and they interact really well).
It does have a slower feel to it than usual, you don't get that typical sense of urgency; the stakes are high, yet it feels 'insulated' - perhaps as a result of the future setting. But it's enjoyable. 7/10
