Nick of Time is one of my favorites, and TwilightZone competes with Trek as my all time favorite tv. I don't think I could trade Trek with the Zone as a whole franchise. If nothing else, there's more Trek, but I might be willing trade a single Trek series for the original TwilightZone. The hard part is deciding which series I'd never get to see again. I could cheat and say Discovery, but for a real pain point, probably TOS.
