I'm about 5-6 hours in, and this game is so weird and feels like a step back from its predecessor in many ways.
The strengths of XC were the charm, the heart, and Shulk himself. Here, we get a mute nameless protagonist with no real agency, just getting bossed around by people. You spend so much time watching cutscenes of people slowly explaining the geography and the factions and whatever, all things better shown than told. The combat feels less satisfying, perhaps due to the focus on ranged ballistic weapons. The music feels very tone-deaf, especially the rap stuff, and pretty much nothing from the previous game is improved. The sidekicks aren't as interesting as the ones from the previous either, with no attachment to them or their motivations. In general, there's no motivation. The story doesn't really give me anything personal I can attach to or any reason to invest. It feels like a very paint-by-numbers game with no soul. The world design and art direction is amazing, but that's pretty much the only thing.
I'm only continuing to play this because of the faith I have in the franchise, otherwise I would have just dropped it. And before you go "give it more time to get better", the original game was charming and engaging from the start. It immediately gave you a reason to care about the characters, the story and the world. And didn't make you sit through hours of uninteresting dialogue explaining the geopolitics of the region or how the army is structured or whatever.
