(Wow, what is this, my 6th post on this thread?)
People don't like things. When people don't like things, they do one of three things: Get over it, keep it to themselves, or, the most popular option - whine about it on the internet. Unfortunately, there's no law of the internet (Not like any of its laws are ever kept - except Rule 34) saying that people can't whine about stupid things, so they get away with it. No matter what, they keep sobbing and snapping about how "things should have gone like this" or how "they shouldn't have done that".
Despite how catchy/cute/neat the new names are, people will, for one reason or another, hate them. Things would be no different if the 1st gen was switched around with the 5th gen - people would still complain about unoriginality, lame names, stupid songs, etc. Come on, admit it - it's true.
