Supacell deserves a 6.8 at minimum!!! I just finished it, and really really enjoyed it. I'm a sci-fi connoisseur, especially British sci-fi. I'm glad I took a chance on it, even though it had a 5.8 when I started it. Based on the description I was initially worried that this would just be a knockoff of the cult classic Misfits, but I was pleasantly surprised!!! I would consider it a mix of Misfits and The Lazarus Project, but with its own intense atmosphere.
One of the main characters is part of a violent gang, and that's an intense part of the plot. I'm a privileged white American who's never been impacted by gang violence so I can't speak to how accurate of a portrayal this was. But it FELT very real to me. I feel like I got a small window into what that life might be like. Tosin Cole was excellent, and you really feel emotionally invested in his quest. The actress who played Sabrina was great as well. The VFX and SFX for the superpowers were awesome, and most of the acting was pretty good. It has plot holes, as others have said, and parts are predictable. But it was engaging and enjoyable, which is what we all want at the end of the day.
