I just can't get into Star Trek, and I think it's because it's just too episodic. It's hard to get invested in characters when there's not really dynamic elements to them, and it's hard to get into a plot when most of the time it doesn't matter by the end of the episode. It just seems like one of those many things that yes, was seminal, and set the bar for an entire genre, that bar has been surpassed too many times for it to be relevant except to fans.
Very open to being convinced otherwise though.
