I'm not a Trekkie so I'm not really bothered about what this show "should" be and I can see the value in a TV show that caters to people who want to have the characters psychoanalysed in response to their trauma using metaphors to mirror what's happening irl...
... But we weren't watching it for that. Changing the show to be something radically different after three seasons is a terrible idea. You won't somehow draw in a new audience who want to see that, they'd have to watch the first three seasons to make any sense of it, which they won't enjoy. If it's what your old audience had wanted to watch, they would have been watching something else to begin with.
It's not as though the emotions are any more realistic and relateable than befits pop-SF. Enough of the unearned, melodramatic, masturbatory speeches.
