Personally I don't think it's gone too far. I mean there were some really, really bad ones in the first 150; so bad in fact that people fully equipped with their rose tinted classes intentionally block out their names and list them as part of the new ones.
I mean it's not like it's a sudden change. It's been 10 fucking years. They've slowly been adding up pokemon and for those who have decided to keep up, instead of ******, it's pretty easy to differentiate. It especially irks me when people ***** about the names, the puns used for the original 150 were just as bad. I cringed at the names of the originals, when I was fucking 6.
Hell most of the new ones aren't even really "new". They just add evolutions to old ones. Whether that means a new baby form and a new second stage (like Electabuzz and Magmar) or just adding a new one on top of one they already had (like Scyther). Out of all the things people could ***** about, I still can't believe they ***** about this.
* in this context of bitching, I'm trying to differentiate between the people who have no interest in pokemon and the people who tried to relive the nostalgia and are just offended that Nintendo had the gall to change their creation.
