Enterprise started out slow and seemed aimless until they got to the Xindi War arc in season 3. I was pretty much glued to the tv with all the cliffhanger endings nearly every week. If not for the idiocy of how few markets UPN actually aired in, and not counting online viewing into the ratings, (ironic now as it’s the only way to see Discovery) the show could have had a fifth season and had a proper ending. The Mirror Universe two parter was a treat, right down to the mirror version of the credits, and it was fun seeing what happened to the ill-fated USS Defiant from the TOS classic The Tholian Web.
Yeah, there are some stinker episodes, but every Trek has it’s dogs.
