So three episodes in and there's a lot going on. I went into it expecting it to be more CW cringe and it ended up being the breath of fresh air I needed to enjoy super hero shows again.
All the characters are spot on, despite my reservations, and I can't think of anything to actually complain about here. It is just that good.
I would have thought Jordan might have been something you weren't thrilled about, what with his requisite "angry at Dad" outbursts per episode.
Well, there are several facets of that to make it believable for me. First of all, he 'runt' twin has probably spent his whole life trying to live in his super-star brother's shadow. But even in that context, these brothers aren't at each other's throats, they have each other's backs no matter what.
How many dozens of shows have we seen where there's always the 'sibling rivalry' trope to the point they plot against each other. Not here - they have friendly ribbing on each other. I think it's a perfectly normal and healthy example.
As to the kid being "angry at Dad" as you say - he doesn't actually hate Clark, he just feels neglected by him - which he was. And now he's having to deal with a lot more burden that he found out his dad was Superman and it was being kept from him and that he has powers, but in the context of him never feeling good enough, even with the powers, he didn't feel good enough still because Jor El said they were subpar.
But you'll also note that at the end of the current episode, without getting into specifics, we see that while they did engage in the stressed out family drama, they actually moved past it and are still in the process of bonding. I think that's another accurate and positive portrayal of a health family dynamic.
You can have a "normal" family with all the emotional dynamics without it being an "everything smells like roses" and still address the hardships without deadbeat parents and kids who are just completely off the rails full of hate and spite.
And let's face it, there are already examples of the more drastic portrayals of less than healthy family relationships and issues surrounding Lana and her family.
And that's considering the fact that what you call "every episode" amounts to just the pilot and two series episodes. The show has a long way to go before we can say it overdoes anything at this point.
