Re: Enterprise, Star Trek Falling On It's Own Bat'Leth!
It didn't help that the first contact with Klingons occurred in the very first episode, and was about 50 years earlier than had been suggested in the other shows. Then that the first contact with them didn't trigger all the conflict we'd been led to believe.
Then subspace radio shows up before the USS Horizon leaves "The Book" at Sigma Iotia II in 2168, which happened before subspace radio existed.
