A lot of the boss fights were fun but the music was pretty unremarkable and the shine spark puzzles were so hand cramping I gave up on 100%ing it. Plus nothing I was collecting was anywhere near as interesting as what the game just gives you (most the energy tanks, all the powerups, most the +10 missles). None of the new moves were that groundbreaking. Ridley also was not in it.
It was fine, just nothing extraordinary. I think I liked Samus Returns more.
It reminded me a lot of when 360/PS3 games were trying to be cinematic and ruined a lot of franchises. But ironically the more cinematic boss fights were the highlight of the game for me. I just didn't think the rest of it lived up to them.
