We haven't had any challenging champions since...Cynthia (both Alder and Iris are pushovers (as a matter of fact I managed to beat Iris with a Serperior only)), so it's not much of a surprise there.
For what I could see from watching LPs on Youtube, this game seems to be rather...casualized. The Super training makes EV training a joke, the Pokémon Amie helps your pokémon to land more critical hits, avoid attack more easily and even resist fainting and with the Exp.Share and the experience from catching pokémon there's no need to grind (Marriland didn't grind on his run and he was like 10-15 levels higher than the champion by just capturing wild pokémon and battling trainers).
I understand that they did this because they were focusing the game to younger audiences... But the main audience of this game is actually 20+ y.o people (I don't know about your countries but on mine the people who buy Pokémon X/Y is people from 20 y.o and older (old fans from Red/Blue days), while the average teenage/kid gamer goes straight to...Grand Theft Auto).
.P.S.:
Watching this makes me wonder.
Spain confirmed as either 7th or 8th gen region? Sure, why not.
It's not the first time it happens...
4th gen region (Sinnoh) having a French gym leader-> 6th gen region based on France.
6th gen region (Kalos) having a Spaniard gym leader (the man may have an Irish accent, but Ramos has a Spanish name and the looks fitting of a Spaniard village old man)-> ???th gen region based on Spain.
Now seriously, if a new region is bound to appear it would likely be based after either Spain or Germany, since are countries that limit with France (Germany on the East, we on the South) and that would make it easier to make a compatibility with the already existing Kalos (a la Kanto-Johto).
