Overall it isn’t awful. I am a fan of a lot of the DCEU movies but I do think this is in the bottom tier of those movies. The action isn’t well done at all, especially compared to something like Aquaman, and the effects are also probably the worst of any of the DCEU movies. But the acting, emotion, and story are overall solid. I think it’s worth a watch, but I’d recommend renting it months down the line or subscribing to HBO Max to watch it. I personally wouldn’t say it’s worth a watch in theatres though
