Personally, I'm pretty happy for the most part. I'm guessing we're talking about mostly Sun and Moon here. I admit, the game has its problems. Festival Plaza is kind of difficult to navigate. I like it, but there's no denying that. I never really liked the reminders of which moves are super effective against the opponent. And the cutscenes can be a little extensive, particularly at the beginning of the game (though later on, when the story gets interesting, I have no issue with them). However- I'd actually say that, so far, the seventh generation is my second favourite generation. I found the region interesting, and definitely felt like it took a lot of inspiration from Hawaii (unlike a lot of other regions). I found the story interesting, found the Pokemon interesting, everything.
And yes, I admit that the post game is a little lacking. Still, at least it's better than XY's. It's not quite as fascinating as the Delta Episode, sure, but there were at least more things to do, like exploring Poni in its entirety at last. I found myself just as interested by the Ultra Beast arc. And there's at least more battle facilities than the Battle Tree. Still no Battle Frontier, but seeing as the Royal Dome's there now, it's a start.
The story was definitely an improvement, especially from XY. Story may not be everything, but it sure helps. Let's take XY again. I found the story insipid. Nothing felt like it had any buildup. I didn't care about the characters. I didn't care about stopping Team Flare. Really, nothing about XY's story felt interesting to me, save for AZ's backstory. Every character felt one-dimensional to me. I know there wasn't an emphasis on story in prior games that weren't Gen 5, but there was still character development in places. I mean, sure, maybe not in the first Gen- Blue didn't develop much at all. Still, we had reason to care- he was always one step ahead of us, and we looked forward to decimating his team at every opportunity. In XY, though, the rivals just existed. They never gave you reason to fight them. They just existed as a minor obstruction. But with Sun and Moon, at least I actually care about the characters. Hau at least had some development. Gladion had an interesting story. At least the game kept you engaged that way.
As for the 'casual' approach you speak of- I think it's one that's perhaps a little too exaggerated. Sure, it may be easier than ever to pick up the games as an absolute newbie, as well as easier to get into competitive battling. And yes, you are often guided from point to point, but I find that having that market is better than forgetting what you're supposed to be doing (which I have done), if that's what you all mean by hand-holding. But like Scammel said, these are not easy games. As someone experienced with the series and rather knowledgeable about battle mechanics, I can't get through the later parts of the game without some bit of a struggle, even when I have reference for what everyone's teams are and even when overlevelled. I've struggled more with these games than any other. And I loved them for that. I liked being challenged when no other Pokemon game challenged me for a long time. If we were talking about XY, then yes, they were far too easy. But considering Sun and Moon are much harder than them, I really have no clue what anyone's talking about when they claim that they're 'easy'. XY were easy. That I get. But Sun and Moon weren't, at least to me.
TLDR- There should be some improvements, but compared to XY, which I thought were easy and dull, Sun and Moon are a step in the right direction. I can see most of everyone's points, but I don't really agree.
This is just my opinion, though. Maybe it's wrong, maybe it doesn't even make any sense to anyone else. Regardless, I'm sticking by it.
