True. SB had no interest in being a "son" of Superman in his early years of the comics (and also wasn't actually a clone). He was happy being an emaciated minor, doing what he wanted, and having fun and hoping to be Superman one day (which I thought was at least time indicated as something he needed to grow out of and want to grow up to his own hero). When he did have a father figure, it was Dubbilex, but even that wasn't nearly as strong as something like Max and Bart. I miss old SB so much. When they did establish a familial connection between Superman and Superboy was when Superman gave him his name (Kon-El - which is always his "real" name instead of "Conner" for me, unlike Superman, who has "Clark" as the same he identifies as in versions I like best), it was as a cousin, not a son or brother. Superman showed up occasionally to give advice, but he was in no sense a daily presence and Kon never wanted him to be. Kara, on the other hand, did want to go live with Superman when she arrived on Earth in the silver age, as I recall, but Superman stuck her in an orphanage instead.Especially as I don't believe it was a source of angst for Connor in the comics the way it is for the show. Almost his entire arc in season 1 is related to being upset Clark is ignoring him.
More than that, it's problematic to me because they made Batman the "good" parent, when he's been incredibly toxic to his kids in the comics. Normally seeing "good dad" Bruce would be cool, but not when it's just another chance to show off Batman's superiority to other heroes, especially Superman. Which is even more heavily played because of how much more involved Batman in with the entire team (assumably done because the character was already very popular and it would be a good audience draw).WB/DC struggles with keeping Superman relevant for the younger generation, so presenting him as a stiff adult who hurts the feelings of the kid the audience connects with is going to make him look like the bad guy
