Absolutely terrible.
Watch a show like Brooklyn 99 or Sgt Bilko and you'll see you can be funny and irreverent but still follow the basic rules of the setting you've chosen.
Only good thing is that after seeing this I was able to go back and give Discovery a second chance and, in comparison, it was actually watchable.
If they'd kept it to the title and made it about invisible lower decks people it might actually work but they HAVE to make their lead front and center of everything on the ship. Give it another season and she'll be Captain while drawing smiley faces on the back of Sisko's head and calling him Captain Lame-O or something else equally as unfunny
