There are some loose similarities at the beginning and some oddly specific but otherwise superficial similarities later on. Plus the usual weird moments when both shows came up with similar ideas at the same time & found out about it when the other show’s episode aired. #
I eventually concluded I believe the people doing the show when they said it wasn’t a deliberate knockoff.
But I’m still not convinced there wasn’t someone in corporate who saw JMS’ pitch, decided they needed to get out in front of it, and suggested a station-based spinoff to the Trek people. #
