Well, it had a lot of spectacle, that's for sure. Not really invested in the story. You just kinda just go into the raid and kill stuff without much context.
Every raid questline prior went into detail, setting up characters, their backstories, their motivations, the stakes of the conflict, a feeling of history, etc. Every raid questline before this managed to tell a story in its first act.
Here, I don't know what the story even was. I felt like we followed some android who we literally just met into a valley that inexplicably, no one knows about (you'd think Eulmoran airships and Amaro riders would've noticed the place). We do our usual genociding, and then 2P casually tells us "oh yeah, these things are machine lifeforms", which makes me go "what, we're not just eliminating pre-programmed automated defenses, but we're straight up slaughtering sentient life?". Maybe their cute, round character designs should've given it away. Then 2P says "the factory has to be shut down" and doesn't give any explanation as to why. Then we fight the guy at the end (who I presume is another android - he's called 9S), who appears to fighting alongside with these machine lifeforms. Is he defending them? Is he the good guy here? And then that's that. "Cya in 6 months!"
The music was 50/50. Some of the time, it's grandiose and really great, but most of the time it's grating to listen to. I guess it will be more tolerable later on in the expansion when we are walking around in ilevel 500+ gear and can turn those 10+ minute long boss fights into < 5 minute long boss fights.
