XY was decent. It wasn't an amazing game. I also excused its problems thinking that the games after it would get better, which is exactly what happened with GB, GBA and DS games. I had fun playing it.
ORAS was disappointing. First of all, I didn't want it to be a remake, I would have preferred a B2W2-style sequel. Being a remake wouldn't have been a problem, if it was a good remake. I don't think ORAS is a bad game by itself, but it is a bad remake. At least secret bases were good. Got bored halfway through.
SM was boring. Didn't buy it. Best thing about it are the new Pokémon, and being able to pet them. Got bored at the start of the game.
USUM shouldn't even exist. I like the new Pokémon, but the game itself shouldn't exist. This is insulting at this point. Didn't even bother pirating it.
LGPE is offensive garbage. I don't even want to be near to it.
SS is the game everyone (including Game Freak and The Pokémon Company) promised would be good, instead it's boring garbage. It's just insulting at this point. They literally lied when they said that this game was meant for the fans.
