Buah, Smallville. I stopped following that around season 7 or 8 and never watched anything again. For me they just took too long to make Clark Superman.
Smallville was a victim of its own success. It was designed to run for only about 5 years and end with Clark donning the cape and tights for the first time. But then it kept getting renewed over and over again, and the producers and star were unwilling to just do the sensible thing and turn it into a full-fledged Superman series, so it ended up in this awkward place where it kept having to mine more and more concepts from Superman comics but still avoided the actual Superman.
The Kryptonian attitude to send babies or small children in the small ships to the earth tends to get a little silly as well the more often you see it. It seems that this was the standard "save the civilization" plan for both good and evil Kryptonians.
It is a bit problematical. The original idea was that Jor-El could only save his infant son because he didn't have time to build more than a small prototype rocket. If Kryptonians had a bunch of these one-person interstellar spacecraft, it's hard to understand why they didn't have anything bigger and why there weren't already a bunch of Kryptonians off-planet at the time it exploded.
You're actually one of the few people I've seen make this observation, which is surprising to me. When I first heard the show's Reign/Samantha concept, I was like, "Man, that's the exact same frigging thing Smallville did with Doomsday." I admit I was a bit disappointed by how much of a retread it seemed -- though Sam and Davis Bloome are different enough characters, and the story's development has been sufficiently interesting, that it hasn't bothered me as much in execution.
Well, this is a case where it makes sense that they do the same sort of thing because it just works better. I mean, Doomsday was a terrible idea. He wasn't even a character, just a half-assed Macguffin for killing Superman so they could tell a story about what happened afterward. The only way to turn that dumb-as-bricks, creatively lazy idea into a useful character for a season-long series arc was to humanize him, to give him an identity and personality.
Smallville may have done the climactic battle quite disappointingly, but the overall Davis Bloome storyline was a vast improvement on the original.
As for Reign, I get the impression that she wasn't that much more developed as a character than Doomsday was. So she was kind of a blank slate with plenty of room to fill in. And the producers wanted to show the villain
becoming the villain this season, because it was different from what they'd done before. Again, it's an approach that works well for the season-arc narrative structure of modern TV. So a degree of convergent evolution is not surprising.
or the literal translation would be worse.
