It's great that they are releasing these episodes on YouTube. But what a lot of OG fans would love even more is a proper remaster of some of the classics. Unfortunately the lukewarm response to the TNG remaster proved to media companies that such undertakings are not worth the effort. But I wonder if the advent of AI tools has made remasters more economical. I do know there is an ongoing effort by fans to remaster VOY and DS9 with the help of AI but not sure of the quality or cost.
It was never about the graphics though, at least for me. As long as the writing, the stories, the acting, and so on was stellar, I don't mind how it looks (to an extent).
That said, I found the DS9 upscaled you talked about on a torrent site now, and I'll give it a shot.
