I like both designs. There's an elegance about the Enterprise from the Kirk era that the other generations failed to capture. I think the refit is beautiful, but I never did care for the look of the engines. They are boring. I've always thought they look like a vacuum cleaner attachment - the one that lets you get into tight spaces. When you are looking head on at the ship, the engines beg to have some sort of lighting effect, and these do not. Many people have said the dry-dock scene in ST:TMP is too long and boring. I think that's the best part of the movie! It's re-introducing us to our favorite character - the Enterprise. And we deserve to see her in her new glory. I agree that considering the extent of the refit, it's hard to believe it came from the same ship.
