This film pitched a very simple question - 'What if Superman was evil?'. After watching it, I feel like this was a marketing ploy used to sell the script and bring audiences to the door. Honestly, if you take the Superman aspect out of it, this is really just your generic low-budget horror flick. The gist of it is a kid wants to be evil one day and just goes ahead killing people. That's really it.
This is one of those rare stories,that I feel could really benefit from an additional 30 minutes. The fact that the runtime is limited to 90 minutes, results in a lot of rushed scenes, which are consequenced by my biggest complaint, the editing. It feels like they shot all the scenes individually,but had no idea how to transition, so they stitched them together. You're just bouncing from scene-to-scene-to-scene and it's incredibly jarring. There are several moments when I thought, yes, this is interesting,but please slow down so I can marinate in it. Nope,next scene.
There are,however, a few redeeming aspects. The actors do a really good job, and I really wish they had more time to sell us on the material. The gore,is actually quite good; there are some really brutal, bloody moments that I enjoyed. And finally, the creative decision to add Billie Eillish' 'bad guy' was genius.
Overall,I don't really know what you're looking for in this story. If it's a dark Superman twist, you won't get it. If it's horror, it's mediocre. As a slasher gore film, not bad at all. I'd classify this as wasted potential.
