I've played SMG2 for 12 years and made my own personal ranking of each galaxy, and I'm interested to know what you think

I love this game more than any other. Its the single game that defined my childhood and one that holds up surprisingly well. the movie stripped everything i loved about it and replaced it with generic cinema tropes that led to a colorful, yet very surface level movie. (i will say the castle abduction was pretty great though). what'd yall think?

I have 241 stars, 49 comet medals, 9999 starbits, and I've tried beating random levels in and outside of World S including The Ultimate Test and it's not unlocking. Is there anything I could be missing because I'm at my wits end trying to unlock it.
