Not really. In Convergence we get to see Clark about to have a kid. L&C jumps forward ten years, and all the changes and adjustments Clark would have gone through as a father have already happened. And that continued with Rebirth. There was no build-up or development, there was a decade of changing diapers and wiping tears and figuring out parenthood that happened off camera. Even Lois' pregnancy happened off camera in Convergence.
Clark *could* grow to be a good parent. He's got the heart for it. But not getting to see any of that transition (even in L&C) just makes the whole thing so jarring it makes the Byrne era changes look quaint.
You mean the era when he immediately dropped Kara off with people he didn't know on Themyscria? And left Conner, who was all of a few months old at the time (and mentally a immature teen) to the devices of a super shady Hollywood talent agent? And failed to protect Chris? And....did he put Mon-El/Valor/Lar in the Zone during post-Crisis too? I forget. Oh, and there's Power Girl too, his cousin from another reality he almost never, ever interacted with outside of team ups with the JSA. Clark had more interaction and a better relationship with John Henry than he did anyone who he was actually related to, even tangentially.But, not in postcrisis characterisation.
Damn straight. And anyone who looks at the actual publishing history without bias will see the same thing (perhaps "bad" is a tad too strong a word but I don't think we can call him "good" either...at best, he's maybe "barely capable"). When the best you can say about the guy is that "he dropped Kara off with good people" that's not saying much.
