Most of the leaks today are just a lot worse than the recent ones.
The kanto mega-evolutions were good enough to not disappoint nostalgiafags, and most of the other stuff in the Pokémon Direct were good
While the new MegaMewtwo and Megagarchomp are just a bit... lame...
The type chart changes are a bit too much, so people are concerned for their favourite Pokémon, although it does generally balance things pretty well. Scizor will be a bit less OP, for example.
And most of the Pokémon shown were well-received, even if they're not talked about as much. The poodle with customisable fur is cool, for example.
