Agreed. Why couldn’t they have invented a whole new cast? What’s wrong with that? What’s wrong with another cocky young captain? Maybe a full-blooded Vulcan for him to deal with? It’s just a little bit said that they can’t expand their horizon. Wasn’t there an idea for the generation after Next Generation that suffered a setback (i.e., Starfleet is broken up), they’re on their own, with a ship that is damaged, and they have to scavenge parts, find dilithium crystals, etc., while still dealing with other aliens as they try to find allies to rebuild Starfleet? I think that would have been great.
Replace the word "him" with "her" and you've just described the plot of Star Trek: Voyager. (1995-2001). Been there, done that.
