The fact is Enterprise presented them with possibly to tell the tale of the dramatic moments of trek history, the founding of the federation and the first Earth-Romulan War. You cannot get much more dramatic, more sweeping, or more far reaching than that.
Instead, they choose to focus on a stupid temporal cold war uberplot and throw in species, Ferengi, Borg, and etc. that the Federation wouldn't encounter for years. The great sweeping arc of the federation's founding is shunted off and ignored.
It is like setting a story in the political turmoil of the 1930s and insisting on telling the story of the end of the Cold War and the American space program. It is stupid, it is lazy, and it lacks imagination.
Good god. I was 8 the first time I saw the Borg and I couldn't sleep for a few nights I had such heebie-jeebies. Now they are just another Monster of the Week, they don't inspire much of anything, except cringing memories of batmobile armor on Voyager...
Ugh. They need to get real writers on that show ASAP.
