There where no budget cuts due too ratings XD
Family feel... I would argue that they do, but I want to address his judgement on Ash's character.
The characters don't (basically) live together like they do in the older saga's. So he's not really aware of said problems until it's brought into the open... And it's not like he wasn't motivated by rewards or food before (There's lots of instances where Ash is invited into a meal).
Also all of the examples he gave of them being a family and caring for one another where from XY&Z, you could make the same argument if you just watched the first 20 episodes right? that they don't care for each other, and Satoshi only cares for stuff like battles, food, or badges.
Ash is just as caring as he's always been... The Litten episodes, the rockruff, and the Lillie episodes prove that.
Uneven character development isn't new in 100+ episode anime so I'm not surprised. Serana took 40 episodes before she played a role in the story (granted they wrote a great reason why.) All we knew about Serana at that point was that she likes to bake, she likes Ash, and she hates ryhorn racing.
With regards with them not caring for each other and not risking their own safety for their friends... well, did he really just ignore the sandygast episode?
Sophocles? he had 3 episodes that centered around him. We know of his insecurities, he's fears, his weak will. He's a character that keeps to himself yet still yearns and needs the comfort of his friends.
I feel his argument is too weak to hold any water really... But hey, this is nothing new really, remember that people hated XY too... XD
