I just want to know if I was the only one disappointed by the look of the NCC-1701-A.
Since the refit is my favourite Trek ship ever, no, I wasn't disappointed at all!
I think the problem, if there even *is* a problem, is simply one of credibility for me: TWOK and TSFS are emphatic about Enterprise being in her twilight years. TSFS especially basically hangs a plot thread on "She's an old ship Jim, we don't need her anymore". So seeing a new Connie being wheeled out at the end of TVH, although a punch-the-air moment on an emotional level, ultimately contradicts Starfleet's previous stance on them not being fit for service any longer. You don't have an obselete car, but still continue to roll them off the production line just because a minority of people have an emotional affection for that particular make and model.
I have to agree with Mr. Laser Beam
on this. To liken it to your car analogy, if someone had, say, a 1982 Toyota Camry, it might be too old to maintain cost-effectively. But since the Camry is still being made, you can go get a perfectly good 2014 model... which doesn't change the fact that the 1982 one might not be fit for use.
