Scaling the ship up without adjusting the specific details is what makes it seem wrong & silly and implausible,
What details should they have adjusted?
I'm sure someone will correct me if I'm wrong but isn't it the story from the VFX people that the ship was designed to be pretty much the same scale as the original and then well into production they realized that it needed to be significantly bigger to accommodate the shuttle bay, engineering, etc. and so they just scaled down the windows and that side docking port (at least it used
to be a docking port, apparently now it's a recalcitrant crewman ejection tube) and didn't bother to add more windows so that it would look like there were more decks?
