I was gifted a 4K bluray player for Christmas. Whopper!

I immediately bought my favourite movie of all time - Aliens. I only got around to watching it recently and HOLY COW the detail. I grew up watching it on a VHS that I recorded off the TV.

I'm looking for some recommendations for things to visually blow me away. I was thinking of Interstellar, but I did watch that recently enough.

All suggestions welcome and thank you!

edit: Some absolute bangers of recommendations here, many of which I wouldn't have considered. Thanks folks!
