Your enjoyment of this show is going to come down to if you like the Mariner character or not. If you like that character you will like the show. I think she is the Trek version of Poochie* so naturally I loathe the show.
*It's a Simpsons character thats meant to be taken as a warning but one that these writers probably saw and said "That seems cool, let's do that and build the entire show around that character!"
