Earlier today I was thinking about the variety of reasons why Star Trek Enterprise was such an epic failure and easily the worst Star Trek show ever.
1. The theme song. For the first time, they tried to use a pop song as the Star Trek intro/theme song. That does not work for Star Trek. Star Trek themes have always been orchestrated pieces that make you think of adventure and wonder. This theme, while a perfectly fine song, does not work as a Star Trek theme in the least. Right off the bat, this intro is a major turn off for any fan of the show.
2. The uniforms. The "still sort of a space uniform but transitioning into a Star Trek style uniform" thing doesn't work. They all look like they're mechanics at Billy Bob's Towing Service.
3. Focus on the characters' stories. Traditionally, Star Trek has let the viewer get to know many of the crew members quite well. Their backgrounds, their story, how they got in Starfleet, etc. BUT, the previous shows focused on the quality stories of the various species, exploration, battles, etc., and only occasionally done a "character focus" episode, usually seamlessly weaving the characters' stories into the larger plot of the show. In "Enterprise", MANY of the episodes told the "story" of a crew member. This resulted in boring plotlines and also took the "mystery" away from many of the characters.
4. Scott Bakula. The guy looks like a cartoon. Star Trek captains have always had a certain strength. Bakula completely lacks this and comes across as a joke of a captain.
