Well, the reaction on this forum is about what I expected
.
In all seriousness, I think this show will allow Hoechlin's Superman to shine in a way he hasn't in the past now that he doesn't have to be used as a supporting character to Kara. Even the parent deal won't get in the way of the fact that he's the main character in my opinion. And Jon might be at an age where they can't do very much with him unless they time skip to him being a teenager.
I do wonder what they will do with it beyond "Lois and Clark tackle a case/parent issue of the week" since
Supergirl has already established several iconic Superman villains (including Lex). Will they be able to differentiate enough from Kara's show? I guess they can re-establish Zod, they haven't done anything with Brainaic yet, and maybe Mongul?
It's a shame they can't reboot Jimmy for this, but I guess we'll finally get to see Arrowverse Perry White? I'm curious what the supporting cast might look like.
I wonder if they'd eventually do a season adapting
Death/Reign.
