Me too! This is kind of what I was hoping for from a Superman show. A combination of the best elements of both versions. I really hope this does well.
In terms of the ages of the characters, I always kind of thought that Hoechlin was too young to be a Superman that was supposed to be the age that found Kara. If we were talking about one who was just starting out, I think he'd be fine. But he's essentially playing a character ten years older than he is in real life. So you have this baby faced Superman who is supposed to be (estimated) 40ish. It's a little off putting. And now they're going to saddle him with two teenage sons. Played by 20 year olds. I hope that visually I can get used to it but right now my brain is having a hard time suspending disbelief.
