A few things:
I personally feel as time goes on, while it's understandable, it's getting increasingly pointless to feel so much anger at this game for being "casual". It's becoming more and more clear that LGPE is appealing to a different demographic, and I don't think there's anything wrong with that. Yeah, it might not be my cup of tea personally, but to say it lacks any sort of charm or draw would be misguided, I think. I personally think this would end up being a very "what you see is what you get" type of game. Everything is stripped down barebones to make things as simplistic as possible, which to be honest, might be preferable for some. It means you won't have to worry about soft-resetting for Natures and correct Abilities for one, so maybe this would end up working in the long run for some people, anyway.
That said, there's a different debate/discussion on whether LGPE would be the start of either a new series, or a foundation of how Pokemon gaming will be on Switch from here on out. I'm really interested in how others would feel about either option, but I think whether you like these games or not, it's going to be hard to turn a blind eye to them because I get the gut feeling that LGPE is going to leave its mark in subsequent Pokemon games. To what extent is something we'll see, of course. And of course this could all depend on how well these games sell, but don't be surprised if you see elements of LGPE (whether it be the graphical style or whatever) reused in the Switch main series games moving forward.
A big criticism to Game Freak (or TPCi, I'm not sure who really authorized this but it's probably both) is paywalling a rare Pokemon for the sake of raising merchandise sales. Part of me feels like this is partially business genius in a sense because Mew is popular, but part of me feels like it's rather scummy at the same time. $50 for a controller that works with one game and one game only (assuming LGPE is the only one in its series), even if it comes with a rare Pokemon, is a high price. If it's absolutely necessary, I would've been ok with $25-30 as the price tag, but nothing higher than that.
TLDR: Much like SM and USUM, Game Freak is exploring outside of their comfort zone. This, of course, is a divisive move like it always has been. BW and B2W2 weren't exempt from this because they got the same treatment. Whether this "experiment", so to speak, pays off will probably determine what Game Freak's priorities are come 2019 and beyond.
