Eh... that's just cuz you're old.Hurray for them, but I want more new Trek that's based off of those series, personally.

As long as the Enterprise has a saucer, a low-slung engineering hull and two warp nacelles, yes they are.Except when they aren't minor cosmetic changes.Since Star Trek is not a technological documentary, the cosmetic appearance of the ship is about as minor as it gets.
So let's have a look.
Saucer module - CHECK
Warp nacelles - CHECK
Engineering section - CHECK
Shuttle bay - CHECK
Deflector dish - CHECK
Bridge on top of the saucer - CHECK
Registry NCC-1701 - CHECK
You have these things and you have The Enterprise. The details of what each of these elements actually look like constitute minor cosmetic changes. To put it frankly, I actually like MOST of these changes. It's not as attractive as the TMP refit, but then again neither is the ENT-D. It's one of those designs that grows on you over time the more you see it in action.
Then your opinion is thoroughly irrelevant and I can go on ignoring you.Hurray for you; I never claimed I had any authority other than over myself...
