I quite liked the Starship Troopers film, though I only read the book years later - but I remember people being cross about it not being like the book.

The Foundation books I’ve read a few times each over the years, but I suppose it depends on the extent of changes - the books cover a huge period of time, and from such a “macro” view, so there’s plenty of stories that can fit in those universes without contradicting the original material.

I liked the recent Handmaid’s tale TV series, having read the book at school (and for fun, some years later) - that totally did its own thing after the end of the book, but I thought it followed a pretty realistic path, and carried the spirit of the original.

I’ll definitely give the Foundation series a try if they show it on something else at some point :)
