I have noted my dissatisfaction before with the awfulness of Enterprise; enough so that I always called it “quasi-Star Trek” due to the many violations of Star Trek canon. Producer Brannon Braga apologized for the horrible ending of Enterprise noting that it did not even live up to his own expectations for what he wanted in the final episode stating:

My analogy with Star Trek is I divorced my wife, I love her dearly, she’s with a great guy, and I’m so happy for her. At the same time, in the back of mind, someone else is with my wife. That’s how I feel. I can’t help but feel emotionally attached to Star Trek. But predominantly my feeling is it’s in great hands with J.J. Abrams and I can’t wait to see the movie.

While the apology on the ending was nice (although really should have apologized for the whole thing), I think the thing that bothers me the most is that since he knew it was going to be the final episode, you would think that he would have scrapped the ending once he saw it and do it over for a proper Star Trek send-off.

Then again, he never cared for the canon anyway, so really never should have expected anything more.
