Again, none of that is what (most) people are complaining about.I think people were expecting a super-detailed amped up version of what we saw in the TNG era. But in Matt Jeffries original design he said the surface would be relatively detail-free since they don't want to go outside to fix stuff all the time.
The two biggest flaws are the damned TRIANGLE and the TINY SAUCER. They look ridiculously bad. But as much crap on them as you want, remove as much crap from them as you want, paint them any color you want, and they will still look like complete and utter shit. It's a core, fundamental design flaw. It has nothing to do with anything else about it. In fact, I personally like the coloration and detail we saw of it in the teaser. But the basic shape and look of the ship is vomit-inducing.
