It's hardly the end of the world, for sure. I just see them pulling the reigns in tighter, which was already happening. So, they will go in to financial restrictive measures to save money, which is what they are already doing.I've mostly seen horror at the idea, given the reputation that Zazlav has right now. I think from a fan perspective that acquisition by Skydance (who would retire Paramount+ and just turn the studio into a content farm ala Sony) is much, much better.
That said, I don't think Trek being owned by WarnerDiscovery is the end of the world. Say what you want about them, but they don't let their tentpole IP franchises die.
That's about the extent I see happening with Trek. Down to one or two shows, if that, and focus on releasing physical media to augment sales from previously streamed shows.
