I think you're complaining about nothing. Infinite Tsukyomi exists to make the desires of the victims "come true" Notice how in most of them (barring Ino), that the ones close to them that have died are in there? It fits perfectly, they achieve their desire for themselves while the ones close to them are still in there.
For instance, you're complaining about Hintata being focused only on Naruto. That's not what I see. I see someone who has everyone she cares for as 1 big happy family. Neji and Hanabi, for instance, look perfectly comfortable around each other. This tells me that A. she want Naruto(big shocker) and B. she wants their to be peace in her family above all else. It's not vain. She's not ignoring Neji at all, the fact that he's there shows she misses him. There's only so much one can put in a single panel, that single panel seemed to put in all of Hinata's core desires in one panel. I could make similar cases for the others as well. (Ino is a disgrace though, won't argue on that)
Understand this, the entire world of this illusion revolves around the desires. Not every desire we human beings have is right, which is why we don't indulge in them. However, I'm pretty sure if a world revolved around our desires, we'd come across as disgusting as well. If anything, this adds realism to the Naruto characters for having desires not exactly right.
