If you are willing to accept the recasting of all the original characters I see no reason why you can't accept the recasting of the Enterprise too. Just because she looks different doesn't automatically make it bad.
True. Fans have no choice but to accept new actors in the roles, but changes to the Enterprise are not necessary
. It's like comparing apples and oranges.
However, even though I'm not immediately impressed with the image of the new Enterprise we've just seen, I'm still willing to wait to see what transpires. After all, the Enterprise on the assembly line might be expected to look a little rough.
