I think there are plenty of aspects about the game that a lot of people won't like that are causing legitimate complaints.
Putting aside what I think most will agree is a terrible interface, the poor tutorials/tips to educate the player leaving them confused, the heavier controls and the crucial 'cores' mechanics which I had to learn from a game guide and RDR2 really isn't a Red Dead game, its a cowboy simulator branded as Red Dead in the Red Dead Redemption universe, which which I don't think many expected/wanted.
Rockstar didn't dip their toe lightly in RPG, it looks like they went all in. Except, most of it can be ignored but the game does a poor job of explaining almost everything. E.g. camp upgrades via the ledger outside Dutch's tent is mentioned once in a post-quest cutscene with Herr Strauss and, as far as I can see, never mentioned again. That said, camp upgrades are optional unless you actually use the facilities at your camp, if you don't then you can ignore it all.
Then there is the very limited fast travel which, if your gaming time is limited, is really going to grate as you'll be riding around a lot. And because the quests can be completed in any order you can end up riding a lot where there is certainly a more optimal sequence where one quests leaves you closer to another.
After about 15 hours I'm really liking RDR2 but I can see why a lot of other people wouldn't.
