On topic, I do see what you are getting at with the names and such, but every Pokèmon retains the awesomeness of the game before it and adds more. If that wasn't the point, they would've stopped makng games at Gold/Silver.
While Black/White may be, in your opinion, a bit lacking in certain aspects, I'm sure there are many other parts of the game that make up for it. In my opinion, what I love about the Gen 5 games is the technology. I remember when I got Diamond - I got to Jubilife City and went "OMG A WATCH COMPANY." But eh, that's just me and my eccentricity.
I think Black and White are just as good as their predecessors, although my favourite is Emerald (everyone has a favourite
). Off-topic(ish), I think a DS remake of Ruby/Sapphire/Emerald would hit the spot. :)
