Sun and Moon pros and cons.

Pros
>No ugly chibi style
>Gen 1 pokemon recolors/variants
>Z moves are ok
>Ultra Beasts are cool
>Tapu are cool
>No more HM slavery
>Lots of cosmetics
>New pokemon are mostly alright
>Team skull is hilarious/teaches kids gangs are lame
>Alola is neat

Cons
>Cutscenes. Takes like 30 minutes to start a new game.
>Popplio's whole evolutionary line
>Difficulty
>No New Game+
>No rebattles
>No gyms
>Cutscenes. See how I put this in twice? That's what the game does. Puts cutscenes where they shouldn't be.
>Plot. I haven't cared about a plot since generation 4
>Mega evolution still exists
>Waifus.
>S.O.S. battles, so fucking annoying. Only way to chain? Really? Because the DexNav was too much fun?
>Battle Royale
>Zygarde cells
>Cutscenes. It's really this bad. Every new minor plot point is an unskippable 2 minute a spamfest
>Fishing changes
>Hyper training

That's my list. Feel free to add or argue or refute my points, these are just my honest opinions.
To be perfectly honest, S&M was mediocre at best. They at least added a lot of content.
But they changed things that were working well, and i'm still butthurt about mega evolution.
